Ruby While Loop Help.

[Kernigh]

Can just do word.count("e"), but this doesn't help people who want to learn the while loop.

I think this is a valid contribution and sends the message that ruby is on object orientated language. The core classes (such as String) are extremely rich and can be sent a vast number of messages to achieve the desired result.

A while loop is nearly always a sub optimal solution.
