I suppose my vote bumps it up from -1000 to -999. /shrug

Dot as postfix function application is frankly a great idea that exists in many many languages. It's great for intellisense and it's often great for reading code left to right. It may not be the best fit for Haskell, but Haskell has never been one of those "one right way to code" sort of languages.

was originally part of ORF, but dropped to keep the scope/discussion more
manageable. Now that ORF is in for GHC 8.0, I would like to re-propose dot
postfix syntax.

The idea is that instead of

(title person) ++ " " ++ (firstName person) ++ " " ++ (lastName person)

we could have

person.title ++ " " ++ person.firstName ++ " " ++ person.lastName

This is a simple source-to-source translation with no changes to the type
system (TDNR is an orthogonal proposal). The advantages are:

  1. Code that's easier to read/write.
  2. Familiar to users of almost every other programming language.
  3. IDE auto-complete - an IDE can suggest functions applicable to the
variable after typing .

This would be an opt-in extension.

I'm posting this to the libraries list because that's where proposals
generally go, although this isn't strictly a library issue. If it should be
on a different list I'll move it.
