Except for the fatal flaw of that construct: it doesn't work with
all values.
Let's say that you want to include a $4.99 fee in your app, but if
the person is a member of a certain group, you want to waive the fee.
So you write:
(person in group) and 0 or 4.99
This makes the problem obvious; when you have variable names in the
expression instead of an explicit zero, it's harder to catch.
