  You can get close to this with the org.conman.cc module [1] for Lua.  This
will allow you to compile C code from within Lua and have the results
immediately available for use:

  It's based upon my bindings to TCC [2][3], and it also extends the module
system so you can load C modules directly into Lua from source (only works
for Lua 5.1 currently).
