[go-nuts] Indexing a map by a bitset / an array / a slice

Hi all,

I'm trying to a map indexed by a bitset, or more generally, if you will, a
map indexed by an array / a slice.

The problem is that I don't necessarily want to define my array length
up-front: my index keys could be of any length, or a variable length read
from an input file.

I can't work out how to accomplish this in go, because I can't compare
slices.

Of course I can encode everything to a string, then work with those, but
it's messy. I'd much rather find a way to manage it using bitsets as the
map keys.

All the best,
Craig
