And this script supposes to work everywhere. It allows to get the name
of any function from within the function itself.

In the past I have found that approach does not work for anonymous
functions (by definition!).
var anon=function()
{
var myName = getFunctionName (arguments.call *ee);
alert(myName);
};
anon();

But how does it suppose to work for anonymous functions? Anonymous
functions do not have names, this is why they are anonymous!
getFunctionName will return in such case the string "anonymous" , and
it's holly truth.
I could change it into some getNameOrNameIt , so it would clone
anonymous functions on the spot and give them names, but it would be
the whole new story. And why?
>But how does it suppose to work for anonymous functions? Anonymous functions do not have names, this is why they are anonymous!
That is the point that I was making.
And it can never work because more than one variable could hold a
reference to the anonymous function. Some people do get confused with
that.
And why?
See my notes on serialisation to your other post.

Never say never possible!
It's the first rule of every web-development victim :-)
But what situation are you conserned about? I'm just a bit cloudy here.
What anonymous functions can stop you from serialization? Intrinsic
event handlers or custom objects' methods? I don't see any other
*valid* reasons to have anon functions. Or yeh, and runtime assemply
using Function() but it's ugly and I did not see it in a wide use.
Could you give some code like "this and that, and here we have to stop
because..." ?

One should not set a background colour with an unknown foreground
colour, not vice versa.

Edit me if I'm mistaken but IE4 (Oct. 1997) is out of the scope of
support in the year 2005, as well as NN4.
BTW: IE3.1 was released just one year earlier (Oct. 1996), so why
wouldn't include it also?
Actually IE5 (Mar. 1999) should be forgotten by all means too (6 years
is the age of dinosaurs for browsers). It remains a bizarre exception
because in 6 years and till now Macintosh did not manage to produce ane
decent browser for their OS. So we semi stoke with this ancient product
when a maximum compatibility is needed.
IE5.5 (Jul. 2000) is really a border line. After all Windows users will
finally migrate on XP SP2 (no latter than the end of this year), we can
forget this twilight product with the greatest relief.

Unless Microsoft starts giving XP away for free, I think it's highly
unlikely that home users will be more likely to upgrade then than now.

Why? Because you say so?
Different people have different requirements. I know a number of situations
where NN4 support is still required, and at least several where IE4 support
is required.
It all depends.

will finally migrate on XP SP2 (no latter than the end of this year),

MANY corporate users are still on Windows 2000, with no plans to migrate to
XP.

There are different degrees of support. Expecting browsers of that
generation to be capable of the same things as current browsers is
unrealistic, and on that basis it's fair to exclude them. However, that
doesn't mean code should fail uncontrollably, causing errors or, in the
worst case, crashing the browser.
BTW: IE3.1 was released just one year earlier (Oct. 1996), so why
wouldn't include it also?
IE3 is /significantly/ less capable than IE4 and, though IE4 is
relatively rare, IE3 is non-existent.
[snipped tangent]
As for IE4 compatibility, remove the multi-line flag. You don't need it
anyway.
