What to put in the try-block

[=?ISO-8859-1?Q?Erik_Wikstr=F6m?=]

I just thought of a question that I have never seen discussed before
(perhaps it is trivial?) and while I think I know the answer I realise
that others might have other oppinions, which is why I ask it here.

How much code should one put in the try-block, i.e. if you have code
such as this:

foo;
bar;
baz;
try {
somecode;
}
catch (exception& e) {
// ...
}

and you have to posibility to also put foo, bar, and baz in the try-
block, should you do so?

I think no, since by limiting the stuff in the try-block I more
clearly indicate what might throw (or which depends on something not
throwing) than I do if I put as much as possible in it. Are there any
other oppinions or motivations?

Well that all depends on whether you can recover form an exception in
foo and then continue to execute bar and baz. If not, you may as well
put the lot in the try block.
