I guess it's fixed now? It worked for me, at least.

There is no lists of infinite length in this kata.

Yes, it does.

It might be a silly question, but does for example 937640 ^ (767456 ^ 981242) execute in less than 6 seconds to anyone?

The haskell compiler may be broken. Running tests works fine, but when I submit, I get:

/tmp/haskell116514-14-1keeqmu/undefined.hs:1:8:
    Could not find module `LastDigit'
    Use -v to see a list of the files searched for.

Yes, gotcha. If we're expected to be able to solve infinite-length lists, it would be helpful if that were in the problem description.

@Bodigrim, your comment is marked as a spoiler

I am working in haskell.

Mine also always runs out of time, but my solution should be incredibly efficient. I've been pulling my hair out the past week, because (locally) I can't make my solution take any time at all.
