You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: mod.rs
    path of file: ./repos/kcl/kclvm/sema/src/resolver
    
    the code of the file until where you have to start completion: mod arg;
mod attr;
mod calculation;
mod config;
pub mod doc;
mod format;
pub mod global;
mod import;
mod r#loop;
mod node;
mod para;
mod schema;
pub mod scope;
pub(crate) mod ty;
mod ty_alias;
mod ty_erasure;
mod var;

#[cfg(test)]
mod tests;

use i
    
    pub(crate) fn check_and_lint(&mut self, pkgpath: &str) -> ProgramScope {
        self.check(pkgpath);
        let mut scope = ProgramScope {
            scope_map: self.scope_map.clone(),
            import_names: self.ctx.import_names.clone(),
            node_ty_map: self.node_ty_map.clone(),
            handler: self.handler.clone(),
        };
        self.lint_check_scope_map();
        for diag in &self.linter.handler.diagnostics {
            scope.handler.diagnostics.insert(diag.clone());
        }
        scope
    }
