When applied to a term list [u1;...;un] and a theorem
A |- !x1::P1. ... !xn::Pn. t, the inference rule RESQ_SPECL returns
the theorem
A,P1 u1,...,Pn un |- t[u1/x1]...[un/xn]
where the substitutions are made
sequentially left-to-right in the same way as for RESQ_SPEC, with the same
sort of alpha-conversions applied to t if necessary to ensure that no
variables which are free in ui become bound after substitution.
A |- !x1::P1. ... !xn::Pn. t
-------------------------------------------- RESQ_SPECL "[u1;...;un]"
A,P1 u1, ..., Pn un |- t[u1/x1]...[un/xn]
It is permissible for the term-list to be empty, in which case
the application of RESQ_SPECL has no effect.
