Issue Description:

The docs for Int(_, radix:) lists the regex as being

[-+]?[0-9a-zA-Z]

but the exact regex for the code as is seems to be

(-+?|+?)[0-9a-zA-Z]*|-*0)

That is, it accepts these cases beyond what the docs specify:

  • Any number of minuses followed by a 0

  • A minus followed by a plus followed by any number

It seems unlikely this is by design, and contradicts the documentation by not returning nil in those cases.
