Hi,

I thought about two new = algorithms, that could be named "count_while" and "count_until". Here are t= heir behavior:

What do you think about adding these two components t= o the algorithms library ?

Should the= re be both count_while that takes a T to compare to, and count_while_if tha= t takes a predicate?  That seems like it would fulfill Vlad's desire t= o have the word _if in there to indicate that it take a predicate?
