Is it possible to get more structured information from a Lua error
callback than a "mangled" string generated by luaL_error()/lua_error()?


As far as I know, it's not.

Would there be some lua_State trickery to uniquely identify where luaL_error() was called from? Maybe some twisted native (machine language) stack walk? The daemon currently uses wxWidgets (base) so can use x-platform functions.
The Tilde debugger made by Tantalus adds an error hook to catch the location where error() was called from. It works pretty well:
