Description

Sometimes it's useful to take different partials with different precisions or take some partials symbolically. Unfortunately, the assumption that partials are all of the same type is baked pretty deep into the library at the moment.

Research direction

No files, tests, or entry points are named. Start by tracing how the library represents and combines partials, then identify the assumptions that require all partials to share one type; done means supporting partials with different precisions and symbolic partials without breaking existing behavior.
