in thread Is there a way to compare strings without using an array?

The reason is because say is not (yet) a built-in function. You have to import the function into your namespace first, hence use feature 'say';

Alternatively, you can just use print, which does not implicitly add the new line for you like say does.

print "$_\n" for $line1 =~ /[$line2]/g;

You can also add the -l (dash elle) modifier to your "shebang" line which essentially makes print behave like say:

#!/path/to/perl -l

...

print for $line1 =~ /[$line2]/g;

Hope this helps!

say is a builtin function since 5.010. feature has never exported say. feature tells the parser that say should use the builtin say instead of the sub say.
