Perl has "contexts" as its type system. Sigils are a part of that.

There's a lesson here somewhere that most people don't generally want to understand stuff. So stuff that's the least bit different don't tend to go mainstream, things like Haskell have a hard time. Perl was a bit different but just happened to go mainstream anyway, and that probably coloured people's feelings for it, for better and for worse.
