kral,
Actually, I just missed it when I was doing the benchmark. I would give you an award for having the most un-necessary steps. Let me explain why.

• You use substr to get 1st char even though ord returns numeric value of 1st char
• You use split to get a list of individual characters and throw them away using a slice
• You then use ord again for the test

There is however, nothing wrong with it.

Cheers - L~R
