fold f m
folds a function f
on bindings in m
. Each binding
associates to a zone a boolean representing the possibility that the
zone was not modified, and a value of type y. May raise

, except if two disjoint ranges r1
and r2
of
a given base are mapped to the same value and boolean. In this
case, fold
will call its argument f
on r1
, then on r2
.
fold_fuse_same
will call it directly on r1 U r2
, where U
is the join on sets of intervals.
May raise Cannot_fold
