 I would say that the perl style is a lot clearer about what happens.
 
 If you have a lot of loops inside one another, it needs some figuring 
 out which loops happens to be number 2 at any given point.

I agree that the Perl style is clearer, however, I currently don't
intend to add either to Vala, as both will make the code harder to read,
and I don't see sufficient need for this functionality.

If you have complex nested loops you might want to consider using helper
methods, this usually makes the code a lot clearer.

2008/6/30 Dov Grobgeld [EMAIL PROTECTED]:
 A small syntax enhancement borrowed from Perl that I would like to see in
 vala is labeled loops, that can be referenced in continue and break
 statements. Here is an example:


 pixels:
 while(foo) {
 for (int i=0; i1000; i++) {
 if (a)
 break pixels;
 if (b)
 continue pixels;
 }
 }

 See the last and next statements of perl for a larger example.


Why not just ask for goto, that seems to be what you really want.
