G'day...

Which is better to use, a for/foreach loop or map function when doing
some basic comparisons and assignments?

E.g.

for my $datum (keys %{$rh_vars}) {
        $max_length = length($datum) if length($datum) > $max_length;
}

OR

map { $max_length = ($max_length > length($_) ? $max_length : length($_)
} keys %$rh_vars;

OR

map { $max_length = length($_) if $length($_) > $max_length } keys
%$rh_vars;


Thanks heaps - some discussion on these basics would be great. My guess
is that it would be the last one as it doesn't assign $max_length a
value unless it has to.

Regards,
