Where are the bigger test values?!? Because Javascript's numbers
can't represent values higher than `Number.MAX_SAFE_INTEGER`
(i.e. 9007199254740991), we chose to exclude these final values
to avoid the weirdness. A bit more information can be found
here: https://github.com/elm-lang/elm-compiler/issues/1246
