   even if honestly I still haven't found enough time to start using 
wxLua myself :(, just a dummy advice: I'd keep the auto conversion code 
(it's an important part of modern interpreted languages I think) but I 
understand what you mean - so maybe we could add a work mode to wxLua 
interpreter so that it logs the creation of each new variable (to help 
debugging). This sort of logging has the disadvantage however that the 
log may become extremely long and thus unusable for big programs.

BASIC (I started programming with it ;)) had an "Option Explicit" 
statement which allowed to turn on & off at run-time the creation of the 
variables on the fly:

maybe something like that could be the solution...
