As far as I know one can distribute a program whose source if made of
Lua, plus some (say) BSD-licensed files, plus other GPL-licensed
files. The whole program will then be considered GPL, in the sense
that the binaries can only be distributed if the source is made
available with some freedoms being granted to downloaders, etc.
But users will be free to take the program's non-GPLed source files
and use them for the usual kinds of open-source-but-not-free-software
things if the individual licenses on those files allow that.
