A lot of this looks very nice. One very simple thing I noticed was missing was a binary integer literal syntax. With a systems programming language, it would be nice to be able to write bit sets without shifts sometimes. Just use the obvious '0b10100101' syntax. Also, I think the zero-prefix convention for octal literals is very confusing and possibly error-prone, but it seems to be used even in modern programming languages. Is there a good reason to keep using '0765' instead of something '0o765'?
