Re^2: Matching or masking specific characters in an array of strings

in thread Matching or masking specific characters in an array of strings

Can someone please explain what is happening here? I'm wondering why a solution like this isn't mentioned in this thread - $w =~ s/^aeiou/-/g;

They're not talking about "masking away" characters from a given character set in a single string. They're talking about masking multiple strings together in order find out which characters those strings have in common. Hence:

  southern
- yourself
----------
  -ou--e--

(where - (minus) is the masking operation.)
