	trying to fix function debug name mess without imploding the
		whole system by triggering avalanches of low-level
		software antiengineering from hell...
	...revived SB-INT:NAMED-LAMBDA idea
	unrelated tidying in SB-INT...
	...deleted *OPTIMIZE-FOO* for byte compilation, since there's
		no byte compiler now
	...*PROMPT* has been hidden as an implementation detail
		for some time and no one has complained, so we might
		as well delete it.
