It's worth distinguishing between the _names_ 'b' and 'c' and the 
_functions_ referred to by those names. The _names_ certainly do not 
exist outside of the scope of the function referred to by 'a' (any 
occurrences of 'b' and 'c' outside that scope refer to _different_ 
names), but the _functions_ they refer to certainly do exist.
