sensibility and delete

[ivoysey]

“The deletion rule for Z-expressions in analysis changes not just the
expression being deleted but also the inferred type.  Does this “action
outside the hole” cause any difficulties?”

[ivoysey]

new type -- being the hole type -- is consistent with every type, so there
is no difficulty (indeed, if there were, the corresponding case of
Sensibility would fail to go through.)
