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. Respectfully, Robert Huff
