formatter bug

[kostya]

crashed on this lines:

lib Bla
  type My = ((Int32, String) ->)
end

[bew]

First it is not valid (https://carc.in/#/r/1wwo)
Error in line 2: only primitive types, pointers, structs, unions, enums and tuples are allowed in lib declarations, not Proc(Int32, String, Nil)

The bug here is that code that doesn't compile emits Error:, couldn't format '/tmp/foo.cr' instead of the compiler error message.

The error was semantic, the syntax was OK. It was a formatter bug :-)
