sounds like "Currying" a function but with the parameters taken in any
order, though, in a sense, perhaps not generating intermediate functions...

It's like currying if you could pass g(x) = f(x, y) to one block of
code and h(y) = f(x, y) to another block of code, so that each of g
and h are each like curried versions of f that "bake in" one of the
arguments, without having to know which one will get called first. :-)

So that would be called "Chording"...
(Is there a 'proper' technical term for that approach?)

Not an entirely implausible term :-) The only other implementation
I've ever seen was Microsoft's "Polyphonic C#", which got rolled into
C-omega. I'm pretty sure, though, that it was never referred to as
something you _do to_ a function, but rather as a _different type_ of
function -- as in, the function hasn't been "chorded", it "is a
chord". Very little literature one way or the other though, and this
is the first actual, live use case for the structure I've encountered
in my years of programming :-)
