I also want to remove the M-R, because of various reasons that have
been mentioned before.

However, to stand on more solid ground I suggest that someone runs
some performance tests, with and without
-fno-monomorphism-restriction, to see whether the M-R has any great
impact in practice. There are some performance test suites based on
real code out there, right? Nofib?
