Int Parser on just "-"

[mortigenus]

Is it expected for an Int parser to return 0 when the input is just "-"? I would expect parser to fail unless there's a digit after the minus sign, but I wanted to know what others think before posting it as an issue.
I tripped on this while trying to parse a math expression where I have a literal "-" parser and an Int parser combined in OneOf.

Hey @mortigenus, thanks for the report! I think this is a bug because Int's initializer does not parse "-": Int("-") == nil. 😕

We'll fix it soon or if you have time to give it a shot feel free!

Thanks for your reply, I've cooked up a suggestion #37
