Yes, that's correct... compose() pipes a bunch of passed functions from right to left. Here's the actual type definition if you want to see: https://github.com/googol/DefinitelyTyped/blob/6836f798cb186...

But even at its simplest variant, with just one or two functions passed, what the V0 or T1 do is pretty confusing. I thiiiiiiiiink it's trying to ensure the return type of one function is correctly passed as the input type of the subsequent function, and so on and so forth, but I don't really know.

Also, I should note that I'm using an older version of that lib. The latest version has cleaner typings... still difficult, but at least formatted better: https://github.com/DefinitelyTyped/DefinitelyTyped/blob/mast...
