/*

here i’ll take a break to help myself remember the idea of swizzling operands rather than using inverses. if we consider the output of a function as a further operand, than an inverse is simply a different statement of the same relation between groups of numbers, and operators of different arity can be considered in the same manner. i’m sure there’s some mathematical name for this that i haven’t learned,

so rather than Addition and Subtraction one approach could be to consider something that combines them, where addition is the solution for the largest operand and subtraction is the solution for one of the smaller ones …

/*

so what parameterizes a scalar relation? maybe known functions between some of the operands. for addition we know x + y = z how do i specify this: how about here as a type-templated function associated with two numbered operands?

i’ll want a way to refer to it, so that it can be bundled into an expression …

additionally more is needed than a type-templated function, e.g. i’d want the character “+”

got some confusion here
