MemoizedInstanceVariableName cop suggests syntactically invalid instance variable for predicate methods.

#5445 (comment)

---

Expected behavior

It should suggest replacing @has_something with @something

Actual behavior

Rubocop wants me to change the instance variable to @something?, which is not valid.

Steps to reproduce the problem

def something?
  @has_something ||= figure_out_something
end

RuboCop version

0.53.0
