MethodType is a useful shape for describing a pattern, in reverse; the
“parameter” types are really the pattern bindings, and the “return” type is
really the (minimal) type of the target. With such a description, the
MethodType for a pattern is the right input to get the carrier for the

It is a base assumption that the specific representation — bits in an int[], a
class per shape, a cache of common shapes, etc — is a pure implementation
detail that can be changed at will, based on various tradeoffs like
footprint-vs-startup that can be made at any time. The only assumption is
