I've got a hint from a gentleman here to use the
following syntax.
public static FileInfo[]
GetFilesRegExp( this DirectoryInfo di, string pat)
{
Regex re = new Regex(pat);
return Array.FindAll(
di.GetFiles(),
(f) =re.IsMatch(f.N ame));
}
The problem is that the compiler seems to dislike
"this" in the argument list as well as "goes to"
in the lambda expression.
What's up with that and how do i kill it?

Another reason not to stick to fancy syntactic
sugar stuff like "lambda expressions" and to do
things the old fashioned (C#2.0) way.
I just reviewed lambda expressions this morning,
as well as Action and Func, and it seems an
enormous waste of time, designed to impress
fellow programmers, like the ternary conditional
operator ?:, rather than to get the job done.
Oh, c'mon a bit. Sometimes it's nice to play with
your coworkers and typing some really complicated
code they haven't seen before, nodding the head
and asking, "what do you think, guys?". It's a
great way to learn who's got the cojones to admit
they don't know what's going on. :)
I warmly recommend the language of APL , if one
wishes to impress/scare/astonish colleagues...

Don't worry about Ray. He dismisses as useless pretty much everything in
C# that he doesn't fully understand. I don't think that will ever change.

That suggests you haven't really understood how useful they can be - in
particular, LINQ relies on them.
Lambda expressions are very, very powerful. I just wish Java had them

That's not true. I dismissed as useless delegates until such time
that I started using them.

How about learning it *before* dismissing it as being poor man's SQL? LINQ
is by far the best approach I've seen to integrate relational query syntax
into a "normal" language. Integration has many advantages that are otherwise
very hard to realize, e.g. compile-time type-safety.

Hi,
I'm trying to write a Python function that parses
an expression and builds a function tree from it
(recursively).
During parsing, lambda functions for the the terms
and sub-expressions are constructed on the fly.
Now my problem is lazy evaluation. Or at least I
think it is. :-)

Hi guys,
I'm a little worried about the expected disappearance of lambda in
python3000. I've had my brain badly broken by functional programming
in the past, and I would hate to see things suddenly become harder
than they need to be.
An example of what I mean is a quick script I wrote for doing certain
actions based on a regexp, which I will simlify in this instance to
make the pertanant points more relevent.

During our current discussion of the fate of functional constructs in
python, someone brought up Guido's bull on the matter:
http://www.artima.com/weblogs/viewpost.jsp?thread=98196
He says he's going to dispose of map, filter, reduce and lambda. He's
going to give us product, any and all, though, which is nice of him.

How does the lambda library actually works. How does it know how to
evaluate _1, how does it recognize _1 as a placeholder, how does it
then calculate _1+_2, or _1+2 etc. The source files seem a bit
complicated so any explanation would be appreciated.
Thanks

Hi There,
Can anyone explain me the real advantages of (other than syntax)
lambda expressions over anonymous delegates?
advantage for one over the other.

F fLambda = a =a++;
F fAnonymous = delegate(int a) { return a++; };

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
