Pierre,
Thank you, but I got it to work the way I wanted, thanks to Matthew and
Rob's posts:
map { modify_variable(${$_}) } = \($var1, $var2, $var3);
To annotate to what Paul said - the above won't work. The block syntax
of map is "map BLOCK LIST". Plus, it looks like you are going to

And map in void context is generall

Hi Pierre,
my @tmp = ( $var1, $var2, $var3 );
@tmp = map modify_variable, @tmp;
which is better
Conway (in Perl Best Practices) prefers the block form of map, since in
his opinion, it's more readable. So you could rewrite it as:
my @tmp = ( $var1, $var2, $var3 );
@tmp = map { modify_variab
