Hate is a matter of personal taste, but if you can moderate your hate
of C++ I would advise you to. Much of the really difficult, demanding,
high-performance software in the world is written in C and especially
C++. It is used for fighter plane avionics, Microsoft Office, database
engines, physics experiment data analysis, real-time trading systems,
and so on. Not to mention almost all computer games. The people who
selected C++ for these tasks were not basing their choice on personal
LuaJIT+FFI is very exciting indeed, but until it supports metamethods
for C types and native multi-threading it will not be competing in the
same space as C++ for these kinds of challenges.
Of course I hope that LuaJIT+FFI soon will support metamethods for C
types and native multi-threading...
