You misunderstand me. I am really tired of imperative langauges like
C/C++ .. I work in industry (for a long time) and have programmed in ANSI C
for more than 10 years. Please see my interleaves below.

POSIX instance of "class OS" and a Win32 API instance.. function calls will
be to the instances and hence the OS APIs are visible. Yes?

^^ the problem is that C/C++ is taken seriously even though they are
high level assemblers. C/C++ have monopoly (as I am sure) in industry. It is
almost impossible to convince the software industry to consider FPLs
(assuming they even know what an FPL is). It is the FPL community that has
to proof itself if is to break into the software industry.
