"unexpected INDENT" in Rails Coffescript after Ruby version change

The Original Problem

Changed ruby version (1.9.3 > 1.9.2) and suddenly all coffeescripts started yielding unexpected INDENT.

I've triple-checked for spaces/tabs inconsistency on files, and this is not the issue. When I comment the entire script, the same bug jumps to the next/another coffeescript file.

Tried with coffee-rails versions 3.2.1 and 3.2.2. No success in both.

Anyone to light a lamp?

More Details

I found what causing this, yet I can't understand why it shoud work differently for different Ruby versions. It's a long story, but here it goes.

I use a trick to declare static or dynamic getters and setters to my classes. This is something like:

Function::dynamic = (prop, desc) ->
  Object.defineProperty @prototype, prop, desc

Function::static = (prop, desc) ->
  Object.defineProperty @, prop, desc

This provides me a way to declare properties like this:

class MyClass
  @static 'accessor'
    get: -> _accessor
    set: (value) -> _acessor = value

I have plenty of this all over my code, but after Ruby downgrade the code structure just stopped working. Now I'll have to add a comma after the method's first parameter. Like:

@static 'accessor',
  get: -> (...)

And this is what it was all about. :S

Answer its not longer necessary, but if anyone could explain it... I'd be glad.

This syntax was not allowed "on purpose", if was merely allowed because the compiler refused to generate 'a'(...). ID block is a call

See this issue.
