You're absolutely right. Great analysis.
I've switched to a new job (yes, again!) so have been busy and have paused ZX Basic devel for a little while until I settle.
But the new version 1.9 (still beta) finally allows anyone (i.e. you) to program his own peephole optimizer using a DSL (an specific micro-language). It already works for -O1 and -O2. For -O3 it's a bit harder.
This means that it no longer uses python to optimize code.
But this language (much simpler) and anyone can create it's own optimization schemes and even contribute to the compiler that way.
Indeed this new optimizer already optimizes further (specially 32 bit values)
