[sergeim (Sergei Matheson)]

When assigning to nil as a hash, the RHS gets short-circuited, and the hash assignment on nil returns nil.
To reproduce:

nil[:some_key] = undefined_method
# Expected: NameError: undefined local variable or method `undefined_method' for main:Object
# Actual: evaluates to nil. No errors raised.
