I considered something like that.

My problem was that encoding the parameters of the loop in one
instruction takes too much space. So the first thing I thought of was
to put some of them in the instruction that repeats the loop.

The proiblem was, though, that since the instruction that repeats the
loop points to the start of the loop in memory, it's a
memory-reference instruction, so there isn't much extra room left in
it.

However, there is a little room left, so I may indeed go back and
explore that possibility some more.
