If you allocate a vector on the stack and default initialise
it (i.e. {0}), then by default "is_inlined" = 0. This is bad, as
technically speaking we should expect the vector to attempt to use
it's small inline buffer for vector operations before going onto the
heap - this will mess up our functions. So here I adjust the name to
make default stack based allocation a bit easier.
