Thanks a lot for giving it a spin and for the feedback. Making
magnum.vim was a learning experience, but I'm hopeful that others might
find some use in it. It is obviously no competition for Python.

I was a little ambiguous here. By 'Vim numbers' I meant Vim's integer
data type, which is signed int32 at the moment (see also
':h expr-number'). I agree, floats open up a whole new world of
precision.

I stumbled over this myself, it's a quirk of variable scoping in Vim.
See the note at the bottom of magnum.txt:

Note that due to the way in which variable scoping works in Vim,
you must qualify these variables with |g:| when using them
inside a function.

Thanks for the Haskell snippet, I'll enjoy reading it later.
