Re: Writing extensions which interact (is not fun)

[Doug <douglas.linder@...>]

There's been some discussion of this in the past, if you search the list.

My understanding is basically: Yes, it's possible.

However, you will then get everyone linking their own copy of the lua
runtime into their extension code (because this is easy and works) and
start getting subtle hard to debug errors when the runtime linked is
not == the runtime of the lua state.

I doubt it'd be implemented in the library any time soon.

(You'd basically have to have someone champion it as a cause to
convince people it was a worthy goal and then write the code for it
themselves; and then finally get it accepted as a mainline change; I
foresee some difficulties in that path :)
