Just to add my 2 cents - it's important not to confuse 
for $n (1 .. 100)

with 
for($n = 1; $n <= 100; ++$n)

as the former is an alias for foreach with the localization of the loop variable enabled (for the reasons that have been cited above), and the latter a straight loop counter similar in semantics as C's for() loop.

This reminds me of being bitten by the following several years ago: 

do {
.....
    last if $some_condition;
} while($some_other_condition);

A C programmer would think nothing of this loop. It's a straight do/while loop with a break (or its perl equivalent) statement, right?

Wrong. last/next doesn't work in this situation, because it isn't really a do/while loop, but rather a do BLOCK with a post condition (the while($some_other_condition) could just as well have been an unless() or if()).
