* Fix the `namespace-definition` production The `namespace-definition` production was changed to use `name` instead of `namespace-name` inc1ac531479anda6520fb35b. This appears to be a mistake, since `name` can not produce a `\`. The spec was originally using `namespace-name` for `namespace-definition`. This commit restores that grammar production. * Regenerate using `tools/pre-commit` It appears that the pre-commit scripts were not used to properly regenerate the spec recently. This caused some small styling changes (using html entities for some chars). It also caused a bigger change due to `print` being moved out of the intrinsics section in63d72a6df5. It's not completely clear if this was intentional or not, since `print` is a language intrinsic.
