Bug report

Input Code

[k: ->]

and

[j: -> m is 0]

and

[->]

Expected Behavior

The above should compile.

Current Behavior

It does not compile.

Possible Solution

Context

[->a]

compiles and

[->,a]

compiles

Environment

• CoffeeScript version: 2 only, version 1 compiles
• Node.js version:

Looks like a Rewriter issue.
All of these compiles:

[k: ->,]
[
  k: ->
]

[
  j: -> m is 0
]

[ ->,]
[
  ->
]

Ya I think at least the cases where -> is immediately followed by ] could be handled by a similar fix to #4588

With the other example [j: -> m is 0], I'm not sure, you'd probably have to go a little deeper into the rewriter

All of these are fixed in 2.5.0 except [j: -> m is 0], which I’m not sure is something that should necessarily be supported; it can be compiled if you use multiline style:

[j: ->
  m is 0
]
