Can we support refs to "bool"? #19

Closed Altreus closed 8 years ago

Altreus commented 9 years ago

Perl has a special boolean false, which is simply a dualvar, zero in numeric context and the empty string in string context. You can get it from !! 0.

JSON supports \0 and \1 as shortcuts to JSON::true and JSON::false, but it would be very helpful if it could detect a ref to this dualvar and resolve accordingly.

That would turn constructs like this

($value ? \1 : \0)

into

(!! $value)

Which, although mildly awkward, seems like the sort of idiom we get in Perl, and is understandable after the first encounter.

No. This breaks backward compatibility, and this makes it impossible to tell integer 0/1 from boolean 0/1.
