Class: Henitai::Operators::HashLiteral

Inherits:

Defined in:
lib/henitai/operators/hash_literal.rb

Overview

Reduces hash literals: empties the whole hash and removes one pair at a time. Symbol-key -> string-key mutation lives in HashKeyType (hard set) because framework key normalization makes it frequently unkillable (ADR-12).
