I found a variation of this in the Perl Nutshell book:
$ perl -le '
$foo="fee fie foe foo" ;
while ($foo =~ m/e/g ) {
push @bar, pos $foo ;
}
print join(":", @bar); '
2:3:7:11
Is there an equivalent way to do the same using map instead of an
explicit while loop? I'm guessing not, since map is expecting a list
and not a scalar, which $foo is.
