+1

I like the idea of the vector-safe package. Are you also proposing to
add this package to the HP? (I would also be +1 on that)

I see that the trustworthiness of the .Safe modules is conditional on
whether bound checking is enabled in vector:

#if defined(VECTOR_BOUNDS_CHECKS)
{-# LANGUAGE Trustworthy #-}
#endif

The VECTOR_BOUNDS_CHECKS pragma would not be directly available in
vector-safe. But I guess, by using the install-includes cabal field,
vector can export a header file that exports this symbol when bound
checking is enabled.
