Documentation for int shows succeeding examples as failing

[okkero]

The documentation for Parser.int claims that it fails for the strings "0123" and "123a", however when I run those strings through Parser.int, I get Ok 0 and Ok 123 respectively.

Here is an ellie showcasing the behaviour: https://ellie-app.com/3Kq5dZ5ZBzFa1

I am not sure if this is intended behaviour or not, but at any rate there is a mismatch between documentation and behaviour.
