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: custom.go
    path of file: ./repos/lgo/parser
    
    the code of the file until where you have to start completion: package parser

import (
	"go/ast"
	"go/token"
)

type LGOBlock struct {
	Scope      *ast.Scope          // package scope (this file only)
	Imports    []*ast.ImportSpec   // imports in this file
	Unresolved []*ast.Ident        // unresolved identifiers in this file
	Comments   []*ast.CommentGroup // list of all comments in the source file
	Stmts      []ast.Stmt
}

func (p *parser) parseLgoStmtList() (list []ast.Stmt) {
	if p.trace {
		defer un(trace(p, "LgoStatementList"))
	}

	for p.tok != token.CASE && p.tok != token.DEFAULT && p.tok != token.RBRACE && p.tok != token.EOF {
		list = append(list, p.parseStmtWithFuncDeclImport(true, true))
	}

	return
}

func (p *pa
    
func ParseLesserGoFile(fset *token.FileSet, filename string, src interface{}, mode Mode) (f *LGOBlock, err error) {
	if fset == nil {
		panic("parser.ParseFile: no token.FileSet provided (fset == nil)")
	}

	// get source
	text, err := readSource(filename, src)
	if err != nil {
		return nil, err
	}

	var p parser
	defer func() {
		if e := recover(); e != nil {
			// resume same panic if it's not a bailout
			if _, ok := e.(bailout); !ok {
				panic(e)
			}
		}

		// set result values
		if f == nil {
			// source is not a valid Go source file - satisfy
			// ParseFile API and return a valid (but) empty
			// *ast.File
			f = &LGOBlock{
				// Name:  new(ast.Ident),
				Scope: ast.NewScope(nil),
			}
		}

		p.errors.Sort()
		err = p.errors.Err()
	}()

	// parse source
	p.init(fset, filename, text, mode)
	f = p.parseLesserGoSrc()

	return
}
