So the BASIC way, which is virtually the BASIC-only way, is more
elegant that what 95% of the rest of the languages use (that is,
function calls with parameters and return values)? Sorry, beats me.

You can pass parameters to a macro, it can return a value - what else
do you need? The reason it is not a function is that it can do stuff
only a macro can do, and it is executed at parse time, not at render
time - other than that, it's a good as function (or sub, if you like)
as any. Just read the docs more carefully to learn how to use it.
