Add
key
,value
andhas_index
methods that each take an index.This is needed to allow structural changes to DenseArray in map.v, part of work for #6991.
key
returns a voidptr, not astring
.value
is needed to allow interleaving key,value pairs in memory rather than in separate allocations. This will be more efficient.has_index
is needed because currentlykey.str != 0
is used, which is string-specific.
