I call it macro because it lets you insert basically arbitrary risc code into the ruby level. The way it works:
Reserve namespace X
map any X.some_call to a Mom instruction
by the name SomeCall
which must take the same args in constructor as given
And obviously produce whatever risc it wants
Hoping to rewrite builtin around this idea (with the existing Mom builtn instructions)
Super is a statement, a send really.
Not an expression (as maybe in c++)
The actual implementation will be a bit tricky, like raise, a bit of stack walking, but not impossible. Still, later
