Interesting. If you're compiling your code to Python, you may be able
to, if necessary, adorn a user's variable name(s). I'd be inclined to
use a single underscore notation like _BS_internalname_ and then, in
the event of a collision (which would be incredibly unlikely unless
someone's fiddling), rename the offending variable to
_BS_BS_something_ - which of course you'd never yourself use. Would
that serve?
