Are you familiar with `syntax-rules` based macros? Because this is roughly the same logic here.
It's trying to unify how macros produce syntax objects via `syntax-rules`-style pattern matching and ellipses with how regular pattern matching on values works, so there aren't two separate pattern languages (one for macros and one for everything else).
