 ## Go syntax support
 
-The priority of `llgo` feature iteration is:
-
-* Popular C/Python libraries
-* Full Go syntax
-* Go standard libraries
-* Popular Go packages
-
 Common Go syntax is already supported. Except for the following, which needs to be improved:
 
-* interface (Limited support)
 * map (Very limited support)
 * panic (Limited support)
 * recover (Not supported yet)
-* defer (Not supported yet)
+* defer (Limited: defer in loops is not supported)
 * gc (Not supported yet)
 * chan (Not supported yet)
-* goroutine (Not supported yet)
 * generics (Not supported yet)
 
 Here are some examples related to Go syntax:
 
 * [concat](_demo/concat/concat.go): define a variadic function
 * [genints](_demo/genints/genints.go): various forms of closure usage (including C function, recv.method and anonymous function)
+* [errors](_demo/errors/errors.go): demo to implement error interface
+* [defer](_demo/defer/defer.go): defer demo
+* [goroutine](_demo/goroutine/goroutine.go): goroutine demo
