Well, the current code already prints "unlimited" for
var_integer/var_uinteger.  I'd say it is only logical that they can be
set to "unlimited" too.

Guess your var_zinteger is your "genuine" integer; we probably
shouldn't accept "unlimited" for those.

Of course.  That's the proper type for boolean expressions ;-).
