You have misunderstood. The reason you can do that in Perl 5 is because Term/ANSIColor.pm starts with package Term::ANSIColor; It has nothing to do with what you named the file, it is a matter of namespaces. And Perl 5 and Perl 6 behave mostly the same here (Perl 6 has a few more options).

bash doesn't like nested single quotes, even with escapes. So the first \' gave you a literal backslash and ended the quoted part, then the second \' gave you a literal ' and continued without quoting. The final ' would then open a new quoted string, but bash doesn't get that far because it sees

Re: need second pair of eyes

"use" does two things, in both perl 5 and perl 6. It loads definitions from a file, and it imports things marked as exported. (The first can be done separately, the same way in both: "require" instead of "use".) Normally you will give a file its own namespace with a "module" (perl 5: "package")
