	Is it?  I'll leave this to people with deeper knowledge, but I
get the impression a _lot_ has changed - and not just under the hood -
over the last thirty years.

	The comparison that leapt to mind was to GCC, and its replacement
with LLVM.  I am not a compiler guru ... but I have heard those who
are muttering in eldritch tongues about minor decisions made long ago
that have become irreversibly embedded and block non-trivial
improvements to speed and/or accuracy.
	Now LLVM _may_ be following a similar path - but there seems to be
a vigorous effort to avoid that where possible.
