Ha ha, good point. I question that this is a well-written API: such flags 
to change the behaviour of a function/method are generally poor design. 
If method behaves differently depending on whether or not you want it to 
count something, then it is usually better design to have two methods, 
one that counts and one that doesn't.

In any case, yes, the weakness of naming conventions is that there are 
always odd-corner cases of natural language. Perhaps `name` is also a 
flag telling the method whether or not to name something.

But then, one can write crappy APIs in any language.
