Hijacking Ruby Syntax in Ruby
summary
Demos show concrete hacks: using Binding to read and set local variables at runtime, using TracePoint to rewrite return values and detect class-definition end, and using Refinements to add top‑level helpers safely. Implementations include gems that enforce Java‑like modifiers (final, override, abstract), a table‑style testing DSL, a with/deferral API that mimics Go’s defer, and Ripper+TracePoint to map tokens to semantic context. Warning: TracePoint can break or persist and makes debugging painful.
