Note that, if you use an implementation of such a language in which the
compiler generates C code, you automatically benefit from low-level
optimizations performed by the C "back-end", incl. pipeline optimization
(scheduling). For instance, the Bigloo and Camloo compilers for Scheme and
Caml (ML), developed at INRIA, concentrate on "real issues" and let the C
back-end deal with low-level details.


A side benefit is that the C code produced by such compilers is generally
free from hard-to-analyze features (e.g. aliases) that hinders low-level
optimizations, so that, altogether, the executable you obtain from a
Scheme or ML source is quite competitive with the one you get from
hand-written C code (and of course much easier to write).
