Haskell scripting

What?

Yes, scripting in Haskell for great good. Or: using modern Haskell and libraries to do scripting tasks, without too much boilerplate at all.

Currently also using the new and excellent lens-regex-pcre library, as decent regexes seem useful on the command line.

Why?

To prove (to myself?) it's as easy and fast to run as is now claimed.

How?

Shebangs and Stack interpreter magic.

My turn?

$ app/Main.hs foobar
F-O-O-B-A-R
