Yes. It works with versions 2.x because it transfer function
references from one lua State to the other by extracting the C
function pointer from the source function, and creating a C closure in
the target state using this pointer. I no longer do this because:
1/ it is not LuaJIT-compatible.
2/ after all, the target state calls a function while not having fully
initialized the module/library the function come from, which is a bad
idea.

Unless I have done something wrong, lua51-lanes should be
automatically registered in all lane states, so you don't have to do
anything.
