@ -25,3 +25,5 @@ Hopefully this shows promise. It is an evolution of the concept first prototyped
Note that Pocomath allows one implementation to depend just on a specific signature of another function, for efficiency's sake (if for example 'bar(Matrix)' knows it will only call 'foo(Matrix)', it avoids another type-dispatch). That capability is used in sqrt, for example.
Pocomath also lazily reloads operations that depend on the config when that changes, and if an operation has a signature mentioning an undefined type, that signature is ignored until the type is installed, at which point the function lazily redefines itself to use the additional signature.
Pocomath now also allows template operations and template types, also built on top of typed-function (but candidates for integration therein). This is used to make many operations more specific, implement a type-homogeneous Tuple type, and make Complex numbers be type-homogeneous (which it seems like it always should be). One of the cutest consequences of this approach is that with careful definitions of the `Complex<T>` templates, one gets a working quaternion data type absolutely for free as `Complex<Complex<number>>` (and integral quaternions as `Complex<Complex<bigint>>`, etc.)
