The difference may be that in other languages you are generally working 
in a self-contained environment. Your globals will never interfere with 
anyone else's variable names.

In LiveCode each stack is more of an independent entity sharing space 
with other entities. Suppose your stack declares a global and my stack 
happens to use the same variable name in a handler. With the current 
system, if my own script never declares your global there's no problem. 
My variable names remain local to my handler or my script. With 
explicitVariables turned off, and using your system where I don't have 
to declare the global, my handlers would end up using your values. If 
explicitVariables was turned on, my script wouldn't compile.
