Would it be possible to implement stack traces? It's somewhat bothersome that none are present. Obviously, the issue is that pcall only gives the original error, but would a native os.pcall which gives a stack trace be possible, with the shell using that instead of lua's pcall?

An alternative would be implementing a limited selection of functions from the debug library, namely debug.traceback() in a sandboxed way (discarding any traceback above the computer's bios's level), which could then be used with xpcall.

It is possible to build your own stack trace with error, pcall, and throwback levels... however I do agree that something like this natively would be nice.

This doesn't, however, work with bytecode level errors, such as attempting to index nil.
