Defined in:

Overview

Constants have slightly different properties in their bindings: They shouldn't be rebound. However.... Ruby allows it. It prints a warning when the rebinding happens, but we should be able to detect this statically. Oh, and they can't be bound inside a method. That too is easily detected statically.

Instance Method Details
