Unknown syntax error when trying to pass module as named parameter

[ulrikstrid]

Not sure if you want these issues but the compiler told me to add it.

Repro:

let maker ::SomeModule => SomeModule.make ();

What's the message?

This is a syntax error that we should guard against, yes.

:: is not supported in Reason, please use [hd, ...tl] instead

  We've found a bug for you!

  There's been an error running Reason's refmt parser on a file.
  This was the command:

  /home/ulrik/src/error-test/node_modules/bs-platform/bin/refmt.exe --print binary '/home/ulrik/src/error-test/src/ErrorTest.re' > /tmp/ocamlppc236cb

  Please file an issue on github.com/facebook/reason. Thanks!

This is a weird error as I was expecting it to be a named parameter, was trying to pass a module as a parameter.
