I'm surprised no one has mentioned C as a resonably sucessful multi-langauge
multi-target UNCOL. f2c,p2c,m2c, Scheme->C, sml2c, Mercury, ghc, .... all
compile to C to obtain some pretty resonable performance and a good deal of
portability, with a few warts of course. Compiling to C is really just a
cheap hack to interface with traditional compiler backends so
compiler/langauge implementors don't reinvent the wheel all the time. The
world doens't need UNCOL, just a well designed "universal" backend with a
clean interface. Course the interface may be an UNCOL of sorts.
