code ->forward: any ...

This is the common way to activate code objects. It binds the predefined var objects @arg1 ... @arg10 to the arguments provided to this message and then invokes code->execute on itself. Example:

new(@m, message(@pce, write_ln, @arg1, @arg2)),
send(@m, forward, hello, world).

will print

hello world

code->forward pushes a variable-binding frame, thus limiting the scope of local assignments to var objects (see class assign and var->assign.
