1 while $str =~ s/PAT/REPL/;

Why not just $str =~ s/PAT/REPL/g;? Gives same result...

$str =~ s/A/a/i for 1,2,3;

All this really shows is that without 1 while or the /g modifier that it always matches at the beginning again during reiteration...

I don't mean to be rude, but you didn't really demonstrate anything too revealing :) I'm looking for a case where there is a difference between 1 while s/foo/bar/ and 1 while s/foo/bar/g.
