I think Thomas means you store *all* your cards in a single table, and
pass that entire table to the mhead-hcard function every time you call
it. The function gets the whole table, and it is responsible for
choosing which card(s) to pick from the table, and what to do with them.
In Thomas' example, you could pass it an extra parameter and use that to
pick a card.

The loop you're talking about happens not outside of the #+call, but
inside the function being #+call'd.

Hope that's clear,

E

PS the (card=card-table[0,]) syntax is new to me, is that a
Babel-specific construct?
