I had a fork a long time ago solely to allow the use of "?" in function-names. Writing:

    function alive?
       ... blah
    end

Is so much more natural, after being exposed to ruby. But maintaining forks is hard, so I've slowly gotten use to the standard.

It's a shame that the development is so conservative, and closed, but despite that it is a great language to play with.

    A function that tests for something involving its arguments
    is called a predicate and usually ends in p or -p.
