Returning "!" with a variable that starts with "is" is parsed incorrectly

[bricka]

I have a variable called isEligible. When I write return !isEligible, it gets parsed as a call to !is with a class called Eligible instead of a variable.

return !isEligible

is parsed as:

(source_file [0, 0] - [1, 0]
  (check_expression [0, 0] - [0, 18]
    (jump_expression [0, 0] - [0, 6])
    (user_type [0, 10] - [0, 18]
      (type_identifier [0, 10] - [0, 18]))))

Compare with:

return !foo

which is parsed as:

(source_file [0, 0] - [1, 0]
  (jump_expression [0, 0] - [0, 11]
    (prefix_expression [0, 7] - [0, 11]
      (simple_identifier [0, 8] - [0, 11]))))
