At present, assumeSafeAppend isn't pure - nor is capacity or
reserve. AFAIK, none of them access any global variables aside
from GC-related stuff (and new is already allowed in pure
functions). All it would take to make them pure is to mark the
declarations for the C functions that they call pure (and those
functions aren't part of the public API) and then mark them as
pure. Is there any reason why this would be a _bad_ idea?
If precedent means anything, assumeUnique is pure.
