I have not looked at the code yet, but wanted to comment on the assignment
discussion. IMO focusing on user experience is the way to go. To that end...
* We should use `=` because that is just more obvious.
* We should remove `:=` from the REPL environment (very easy, just delete
`AssignmentCommand`).
* All references in the docs to `:=` need to be changed to `=`. (Ugh)
All of that can happen in this PR or as multiple PRs (however
@ottobackwards sees fit), but that is the right end state.
**Alternative Option**: The only other reasonable option IMO is to support
both `=` and `:=` (for some undetermined period of time.) The only snafu is
that both should have the same implementation. So support for `:=` would have
to be added to the 'language' and we should NOT rely on the `AssignmentCommand`
implementation in the REPL.
I am mildly against the "Alternative Option", but wanted to offer it up for
discussion.
