Now that it can translate labels to offsets, SubX also warns on explicit use of error-prone raw offsets. Both when running and in Vim.

As I build up the ladder of abstractions I want to pull up the ladder behind me:

a) Unsafe programs will always work.
b) But unsafe programs will always emit warnings.

As long as SubX programs are always distributed in source form, it will be easy to check for unsafe code. Coming soon: type- and bounds-checking.
