This cop checks for ambiguous operators in the first argument of a method invocation without parentheses.
@example
array = [1, 2, 3] # The `*` is interpreted as a splat operator but it could possibly be # a `*` method invocation (i.e. `do_something.*(array)`). do_something *array # With parentheses, there's no ambiguity. do_something(*array)
