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 pattern

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

You keep saying “what we need”. But really, what I think you mean is “what the
scheme I have in mind needs.” Can we try and separate these out? I don’t
think any of these are *needed*, but maybe you want to make the argument that
you have a better scheme in mind, and we should choose that sch
Hi Jim,
I believe that there is a mismatch about what is needed for the pattern
matching and the API you propose.
The Carrier API allows to map one tuple of types to one storage representation
based on ints, longs and references.
But what we need is to have several shapes for the same storage, m
