RE: New 'threads' methods

This would be syntactical sugar for:

    my @joinable = grep { $_->is_joinable() } threads->list();

However, I would rather 'enhance' the syntax for threads->list() to take
a parameter to return that kind of information:

    my @joinable = threads->list(threads::joinable);

where the parameter would be defined as a 'constant' in threads.pm:

    sub threads::joinable { 0 };

Similarly, we would have:

    sub threads::running { 1 };

    my @running = threads->list(threads::running);

Or am I making things too hard?
