There are such tag methods because of performance.

Yes, via the debug API (or debug library in Lua).
See lua_getlocal/lua_setlocal and getlocal/setlocal.
But heed this warning in the manual:
You should exert great care when using this library. The functions
provided here should be used exclusively for debugging and similar
tasks (e.g., profiling). Please resist the temptation to use them as a
usual programming tool. They are slow and violate some (otherwise)
secure aspects of the language (e.g., privacy of local variables).
