The simplest way of fixing the problem of typesetting parameters before
they are autoloaded is to forbid it.  I can't see any time it could
conceivably be useful to allow it, since the whole point of autoloaded
parameters is that they get set up when they're loaded, and it's up to
zmodload, not typeset, to turn off autoloading.
