bignums don't make much sense for array sizes and indices, indeed
(except maybe for boolean-vectors), but for buffer sizes they would
allow buffers >512MB (tho still <4GB or likely even <2GB) on 32bit
systems without having to pay for the --wide-int tax.

In case there was still a doubt: I fully agree.
