But do we think about arrays differently because there's a legitimate reason to, or because that's just the way it has worked in other languages?
I mean, the fact that a simple:
(def array (elements) (table))
Would bridge that conceptual gap probably means that although it will feel weird using a table as an array, including arrays solely for familiarity is probably the kind of backwards compatability that Arc is looking to avoid.
You're right, we are definitely approaching this from different directions. I do think that a generic interface to mappings is the way to go, so long as the abstraction doesn't leak too much (i.e. reasonably small performance loss).
