Highlighting for ambiguous anonymous functions passed as parameters

[captainbland]

For:

func = (f)->f!

The meaning of:

func(x)->

is very different to (note the space after func denoting that what comes after the space should be a parameter)

func (x)->

Where the first would compile to something like:

func(x); function(x) { };

and the second would compile to something like:

func(function(x) { });

However they seem to be highlighted the same way. It would be very helpful if the syntax highlighter highlighted these cases differently.
