That approach is to compile C into a shared library that is called
from Lua, which is fairly typical except that additional conveniences
allow the C to be written inline and without binding boilerplate. A
related idea is shown in .
I've considered trying a different approach with lua2c  but have
not had the time to go far with it. lua2c already converts Lua to C.
Taking it to the next level of inlining C into Lua would be very
natural because the inlined C can be directly inlined into the
translated C. For example, you can have a Lua algorithm that operates
on both Lua and C data structures without writing a binding to those C
data structures. The C compiler will even optimize across the
boundary between C and Lua, which I understand LuaJIT does not do.
This type of thing might have a niche. The generated C might even be
consumed by LLVM.
