I see a couple of ways:
1. Set a __call metamethod and write
if (DeviceTag() == "Krish") then
2. If all your VARIABLEs are global, then you can set a __newindex
metamethod in _G to save VARIABLEs elsewhere and set an __index
metamethod to retrieve x.value when x is seen and there is a VARIABLE
named x.
9. Wait for 5.2 and set __eq and write :-)
if (DeviceTag == "Krish") then
