Numbers? Memory addresses? Subleq is rather baroque compared to the ascetic world of combinators... ;-)
NB: As a final year project on my CS course in the 80s I did benchmarking on the efficiency of different sets of combinators for executing a toy functional programming language - the simplest set of combinators I used was SK and that was quite impressively awful to do something like multiplication. Quite interested to see how bad a single combinator scheme would be....
