Another admittedly-gratuitous feature that I would like to see is some
rudimentary form of doing math with page variables.  Or would it be
better just to use embedded PHP code somehow?  When I set up the 
example at FASTData/ProgrammingDocumentation, I noticed a similarity to
an invoice form.

(example markup)

:a: 3
:b: 2
:c: cats
:d: (:math {$:a} + {$:b} :)

Oh no, we have {$:d} {$:c}!
(resulting page)

Oh no, we have 5 cats!
