Switch to Types::Serialiser booleans

[aferreira]

This change promotes type compatibility with other
CPAN serialization modules like JSON.

This is another take at #17 – see also #34

BREAKING CHANGE: removes stringification of true()
to "true" and false() to "false". As the packages
Data::MessagePack::Boolean and Types::Serialiser::Boolean
are aliased, it is not safe to include this controverse
coertion (different modules may have different ideas
on what is a useful stringification of booleans).
The "bool" and "num" (0+) overloads should work as before.

@aferreira How does this compare to #34?

[aferreira]

@FGasper I took a lazier route to achieve interoperability – namely instead of also supporting Types::Serialiser::Boolean, the proposed change makes "Data::MessagePack::Boolean" and "Types::Serialiser::Boolean" the same for Perl. So the assertions below will hold.

A consequence of this approach is that the required change was simpler – no need for patches to XS code or adding explanation on the tolerance of Types::Serialiser::Boolean to documentation.

use Test::More;
use Data::MessagePack::Boolean;
use Types::Serialiser;
ok(Data::MessagePack->true->isa('Data::MessagePack::Boolean')); # old stuff
ok(Data::MessagePack->true->isa('Types::Serialiser::Boolean'));
ok(Data::MessagePack->false->isa('Data::MessagePack::Boolean')); # old stuff
ok(Data::MessagePack->false->isa('Types::Serialiser::Boolean'));
ok(Types::Serialiser::true()->isa('Types::Serialiser::Boolean')); # old stuff
ok(Types::Serialiser::true()->isa('Data::MessagePack::Boolean'));
ok(Types::Serialiser::false()->isa('Types::Serialiser::Boolean')); # old stuff
ok(Types::Serialiser::false()->isa('Data::MessagePack::Boolean'));
done_testing;

To my knowledge #34 doesn’t include any breaking changes, so I’d think that would still be a preferable solution—notwithstanding my own bias. :)

Anyway, I think it’s moot until someone else assumes stewardship of the module.

In the meantime there is a (very ugly) workaround solution here:

Thanks. Given that the owner is unresponsive, any ideas on what would be the next steps to get the PR merged to master and released to CPAN?
