Have you considered submitting flycheck-pony to melpa for slightly easier installation and discovery?

Using ponyc -rexpr leaves exceptions/error checking out. For example the following code (taken from the tutorial) does not compile, but it passes checking with -rexpr.

actor Main
  new create(env: Env) =>
    let iterator = ["Bob"; "Fred"; "Sarah"].values()
    while iterator.has_next() do
      let name = iterator.next()?
      env.out.print(name)
    end

Editing a .pony file in Emacs 24.5.1 without saving it, I'm getting lots of:

Suspicious state from syntax checker pony: Checker pony returned non-zero exit code 255, but no errors from output: Building . -> /home/<user>/proj/pony/helloworld
/home/<user>/proj/pony/helloworld/.#main.pony: can't open file
/home/<user>/proj/pony/helloworld/.#main.pony: couldn't open file /home/<user>/proj/pony/helloworld/.#main.pony

Checker definition probably flawed.

The .#main.pony file appears to be a (broken) symlink which Emacs uses as a lockfile to avoid editing collisions.
A temporary workaround (until either an Emacs update handles these files differently or ponyc learns to ignore them) is to add

(setq create-lockfiles nil)

in your ~/.emacs file. See http://stackoverflow.com/q/5738170/588561 for more details.

I thought that wasn't used anymore. We don't have source for it or update it. We should replace it as appropriate.
