----------------------------------------------------------------
The cause is quite simple: there's cartesian product of 8 index types * 31 data
types * 8 combinations of (indices can be null, values can be null, indices can
be out of bounds) which generates a lot of different specializations.

> take.cc is our largest piece of object code in the codebase. This is a pretty
