Good

Added to PHP

this would be much easier and less confusing, if we'd use "_" instead of " " characters.

Good one

Thanks for approving :)

Thanks for fixing :-)

FIXED GROOVY VERSION

This fixed @Unnamed's issue

Well that's a pretty embarrassing mistake. I published a fixed version here

Let me look into this

Could you please take a look at the issue at the top?

Fixed

Looks like there is a small issue in tests in Lua.
Passed in and expected arguments in assert.are.same(a, b) are swapped, so the outout is a bit confusing.

should count all vowels
Expected objects to be the same.
Passed in:
(number) 5
Expected:
(string) 'some wrong answer'
Completed in 1.0421ms

Of course, it is possible to figure out, but still.

Groovy, sample tests:

./src/test/groovy/fixture.groovy: 9: expecting anything but ''\n''; got it anyway @ line 9, column 75.
