The first one.

Note that optional () is ambiguous by definition - the word 
optional convey this very idea. The ambiguity introduced by 
optional () must not be conflated by the one introduced by the 
existence of non first class function.

You stated that the existence of function is necessary for 
optional parentheses to exist, and I showed you that it is false. 
Nothing more, nothing less.
