You don't need to know the number of fields in a multislot to match
it. A multivariable $?x matches any number of fields (zero or more)
while a single variable ?x matches exactly one field. So to match the
field "foo" wherever it appears in a multifield, for instance, the
pattern would be
($?x "foo" $?y)
To match "foo" if and only if it's not the first field,
(?x $?y "foo" $?z)
to match the last three fields with the variables a, b, and c:
($?x ?a ?b ?c)
etc. Does this fix your problem?
