I like this approach a lot.  Very clear and readable.  Does it work for
other examples?

SimpleExample:

numerator | denominator | =quotient
numerator | denominator | quotient?
1000      | 10          | 100.0000

CalculatorExample: 

volts | =watts | =points
volts | watts? | points?
3.75  | .500   | false

MusicExample (RowFixture):

title    | artist    | album    | year | =time | =track
title    | artist    | album    | year | time? | track?
S. Woman | W. Report | M. Woman | 1974 | 3.70  | 2 of 7

Hmm... equals is better for the arithmetic examples, it's a wash for the
calculator example, and I like question mark better for the music
example.  

I like '?' better overall because it makes it clear you're asking the
computer a question.  But '=' works well and is more declarative, which
is more like Ward's approach.  Both seem like good choices to me.
 
We could support both, but I'm not a big fan of TMTOWTDI ("there's more
than one way to do it", from Perl): I prefer DITWS ("do it this way,
stupid").
