Subject: [ruby-core:85478] [CommonRuby Feature#12732] An option to pass to `Integer`, `Float`, to return `nil` instead of raise an exception

Issue #12732 has been updated by nobu (Nobuyoshi Nakada).


Since `Integer()` has `radix` optional argument, new optional argument might be confusing.
A keyword argument or a block would be better, I think.

----------------------------------------
I would like to be able to pass an option to `Integer()` and `Float()` so that they don't raise an exception, but return `nil` instead.  For example:

~~~
Integer(string, exception: false)
~~~

The reason I want this function is so that I can convert strings from YAML or JSON to integers if they parse correctly, or just return strings if they can't be parsed.
