As this bug report
(https://bugs.documentfoundation.org/show_bug.cgi?id=109097) suggests
it is highly desirable to improve the lookup time in multi_type_vector
(currently in worst case it takes O(N)) without position hints.
Perhaps one further elaboration here is that we're working on exploring
threading the calc-ulation engine (with some success) - however this
requires avoiding highly granular locking - ie. that we can treat the
various calc core data-structures as immutable during that process. As
such the low-hanging fruit solutions of building caches /
last-position-looked-up etc. as we do lookups are rather problematic.
So - I'm well up for this change - assuming Kohei, and other calc guys
are happy.
HTH,
Michael.
