I think filling the syntax hole eagerly is a bad idea.
Besides that, I don't think making ((%->foo%)) as method(:foo).to_proc seems a good idea,
since foo in ((%->foo{}%)) is a argument name, not a method name.
Ah, ->foo{} did not know that the parenthesis could be left out.
Ok, I'll suggest slight modification then, b/c it still would be nice to have a shorter notation (not just to fill a syntax hole). Could it be a symbol, i.e. ->:foo.
Once a issue has been rejected, is it necessary to open a new case for a modified form of the proposal? In other words is any one going to see the change if it has already been rejected? As with this case?
