From random tests:

5rhmxj .5rhmxj .5rhmxj .5rhmxj .5rhmxj .5rhmxj .

That's a very edgy sentence, with whitespace before the dot instead of after it. Depending on the definition of a word there could be multiple interpretations to it. (And then you might have dots inside a word, etc etc. It goes on to show that you either need a full spec, or you don't want to touch this can of worms at all.)

Also, are words supposed to contain digits? If so you need to specify that. (Also for mixed case characters, but at least that's reasonable.)

This not ISSUE, it's because I wrote send method.

I found what happens I rearange send method. I think this is why.

I look forward to this kata when it is translated into Python or C. For now, I wait.

Much better :D

Just added some this morning ;)

How about the spaces before "!" in "Encore!" and "?" in "Parlez-vous français?"?

Needs random test cases

"Encore !"

this is a great kata ! Merci

This seems very messy, is this what people would use in real world applications? Or is there an easier way to validate dates?
