    Just one question: why on earth would we want "obj.true?" to be differe=
nt
=66rom "obj" from a boolean perspective? It's _very_ weird.

    You could write aberrations like:

-------------------------------- 8< --------------------------------
if obj.true?
    # Do something
elsif obj
    # Do some other thing
else
    # Do a third thing
end
-------------------------------- >8 --------------------------------

Not very readable to my eyes...  and anyway, IMHO, a comparison has nothing=
 to
do with OOP. Objects _can_ be compared, too :-)

    I don't think "true?" adds anything to the language. If you want to use
"true?" because you find it more readable, why don't you simply extend the
Object class?
