I get it now. As I suggested in response to Stephen, [] and [1] spell 
False and True only in boolean contexts (if/while headers) where they 
are implicitly wrapped with a bool() call, which is to say, where their 
boolean value is extracted from them. As you point out, there is 
information loss as all other context-irrelevant details are ignored.
