Description

Using the standard Julia type hierarchy limits people to do <: Number when defining a type, but this is not generally doable for generic codes. I wonder if we can use isreal, iscomplex, isscalar, ismatrix, etc to do the dispatch.

Research direction

No file, test, or entry point is named. Start by examining how ChainRulesCore currently relies on Julia's standard type hierarchy for dispatch, then assess whether predicates such as isreal, iscomplex, isscalar, and ismatrix could support generic-code dispatch. Done would require an agreed design and clearly defined implementation scope.
