The difference between an array and a proc doesn't matter, at least
not when parsing. [] in such a context is simply a method and
dispatched as such.
The discriminator is whether foo is determined to be a local
variable or a method.
If foo is a method, foo [2] parses as:
(fcall foo
(array
(array
(lit #<2>))))
If foo is a local variable, foo [2] parses as:
(call
(lvar foo) []
(array
(lit #<2>)))
So, yet another place where this local variable versus method name
thing really matters.
