Duplicate of what? This cata was created 4 years ago

This is a great kata! The biggest difficulty was ofcourse unary minus but it was a pleasure to debugg great task :)

For others: read the text carefully, I missed a few words and lost a lot of time because of it.

Great idea for kata.
Thanks to you I found yet another way to deal with generators :)

This kata made me think about how great metric system is.
Still good exercise ;)

There should be some example tests.

Thanks for suggestion, I will create random tests in near future :)
Random tests are done and I think I broke your solution : (

You are absolutely right - copy paste mistake :)

You are right, fixed thanks.
