Added a very rudimentary file I/O system suitable for experimenting
with the language further. A better one will be designed when we have
sensible error management.
- InertAtomic replaced atomic_inert! for improved tooling support
- atomic_defaults! is easier to type out than to explain in a docstring
- Changed rustfmt config to better support tiny functions such as as_any
- Import paths are now vname and not sym
- Imports and exports accept multiple space-delimited operators in []
as a result, we can now reliably import and export the operator *
- error reporting ergonomics
