* interp: fix creation of binary composite types Use direct assignment instead of reflect.Value Set method to initialize a binary composite type, as for non binary types. It ensures that a new reflect.Value is stored in the frame instead of modifying a possibly existing one, which can defeat the purpose of initializing variables in a body loop. While there, remove the need to have and use a mutex on types. Fixes #1381. * review: rework a bit the test Co-authored-by: mpl <[email protected]>
