Not an issue; it's your fault to fail to catch the general pattern in the tests.

Oops, I was wrong :P

old solutions are now valid, but not the new ones...!

In the beginning of the tests.

I can see how this would work, but I'm not so sure how to do it. Where do I put this in the solutions?

All fixed now. Please refresh your page and try again.

Changed it to snake case this morning and forgot to update the tempplate solution.

Check now, and be sure to refresh your page.

The python method is misnamed, so the tests will not run successfully.

@KenKamau: you forgot to update the solution setup, in python! (and you could have add retrocompatibility with older solutions...)

Thanks. Will respond shortly.

Haskell. Sorry, I forgot that output ends up in the wrong place in Haskell. The tests are:

[0,1,2,3,4,5,6,7,8,9]
[3,2,1,0]
[0,1,3,-2,5,4]

You can do

try:
    is_odd_heavy
except NameError:
    is_odd_heavy = isOddHeavy

so that old solutions remain valid.

Which language? Also, this is a fixed test which requires a false, so I'm not sure.

There's no one true style guide for Ruby but every one I can find prefers snake_case, just search. Maybe you can find something different...

Yes, but expected was True.
