Okay, that I can see.  Of course, leaving it in once it gets into production is a different
matter.

Two comments:

1.  The connect() subroutine wasn't actually being used (the programmer had another connect()
function in a different class -- most confusing).

2.  Dominus' slides reminds me of a comment that a chess grandmaster once made regarding Bobby
Fisher's playing style:  "I can see the brilliance of his positions.  I just can't figure out how
to get there." :)

Dominus does some fascinating stuff and I can see how he does it, but my mind sees things in a
procedural or OO fashion.  Functional programming is still a bit bizarre for me.

Cheers,
Ovid
