Overview
This module is part of a private API. You should avoid using this module if possible, as it may be removed or be changed in the future.
Identifies repetitions ‘csend` calls with no arguments:
foo.
foo. # => repeated
foo..baz.qux # => inner send repeated
foo..baz.other # => both inner send repeated
foo.(2) # => not repeated
It also invalidates sequences if a receiver is reassigned:
xx.foo.
xx.foo.baz # => inner send repeated
self.xx = any # => invalidates everything so far
xx.foo.baz # => no repetition
self.xx.foo.baz # => all repeated
