Some of us have been doing this a while.  Time flies. :)

I tend to think of it as a recent addition because it wasn't until 
RunRev altered its use in their IDE that it became useful.

The impact of the explicitVars global property is so great that almost 
no one in the SC world used it much, and HyperCard, Toolbook, OMO, Plus, 
Gain Momentum, or any of the other xTalks ever bothered with it at all.

With RunRev's more limited use introduced just a few years ago, the 
scope of impact is now small enough that it can be a sensible addition 
to a programmer's workflow without breaking from the traditional nature 
and history of xTalk for every script one might want to use.
