Easy as { 1 2 3 }? (when { 1 2 3 } ≠ { 1 2 3 })

Thanks Joe, that's a good idea. I'll see if I can find references to ROM entries that perform needed translations in those commands. I think I'll start with SIMPLIFY.

FWIW, I've already put together a SysRPL/Saturn routine to do this, which is a fairly good performer (converts a list of 1000 long-form integers in about 0.13s). It converts long-form instances of both reals and zints in the -9..9 range, and leaves everything else as-is. It also converts embedded lists. The only problem with it is that it's a huge chunk of code: 471 bytes (almost entirely assembly). Seems like a serious waste of space for a somewhat esoteric issue that most likely already has a solution hiding in ROM somewhere.
