No, but you can store the last activity you returned; this is exactly what
the CachingActivityMapper does: it'll only call your (wrapped)
ActivityMapper if the Place is different than the previous one, and
returned the "cached" activity otherwise.
Put it behind a FilteredActivityMapper so you can turn different Places to
other ones that could compare equal (e.g. turn any EmailDetailsPlace into a
EmailListPlace, and every PersonDetailsPlace into a PersonListPlace; so
that the CachingActivityMapper can return the same EmailListActivity or
PersonListActivity ("master") instance whereas you're navigating from mail
to mail or person to person ("detail to detail")).
