Returns the number of steps in the sequence.val index : sequent -> unit

Function f
should only transform the head of the predicate, and can assume
its sub-terms have been already substituted. The atomic substitution is also applied
to predicates.

Bundles are mergeable pre-sequences.
This the key structure for merging hypotheses with linear complexity
during backward weakest pre-condition calculus.
