Hum.  Why don't you try comp.lang.ruby.like.but.not.ruby instead?  I
hear it's "phat."

Seriously, as someone prone to lack of concentration, I agree.  A
great many programmers have concluded, probably from painful
experience, that typed variables reduce error.  Also I think that
building error-testing into the code will scale better than reliance
only on unit testing.
	1). I'm not yet convinced that some kind of sophisticated DBC thing
amenable to duckies can't be created.
	2) would be helpful, but it may be a mistake to insist on a keyword.
I think we should concentrate on putting everything that can be into a
DUIIYDLI module ('Don't use it if you don't like it').  Then the
skeptics can't complain.
