Perl programming: continue block

Question

I have just started learning Perl scripting language and have a question.

In Perl, what is the logical reason for having continue block work with while and do while loops, but not with for loop?

Answer 1

From http://perldoc.perl.org/functions/continue.html

If there is a continue BLOCK attached to a BLOCK (typically in a while or foreach ), it is always executed just before the conditional is about to be evaluated again, just like the third part of a for loop in C.

Meaning that in the for loop, the third argument IS the continue expression, e.g. for (initialization; condition; continue), so therefore it is not needed. On the other hand, if you use for in the foreach style, such as:

for (0 .. 10) {
    print "$i\n";
} continue { $i++ }

It will be acceptable.
