as they have their custom filter.

bb6b3a773a Make AST_Class inherit AST_Scope instead of AST_Object 
This is one of those days I'd love to use multiple inheritance.

An AST_Class has lots of common with AST_Object, but unfortunately
`instanceof AST_Scope` is used very, very much, and a class has its name
inside its own special pocket scope. This compels me to make AST_Class
inherit Scope instead.

It looks like, although there is much in common with AST_Object,
`instanceof AST_Object` seldom are made, perhaps because it is less
often necessary to traverse an object than a scope.

7691bebea5 Rework has_directive 
It's now available during tree walking, i.e. walker.has_directive("use
asm"), rather than as part of the scope.  It's thus no longer necessary
to call `figure_out_scope` before codegen.  Added special bits in the
code generator to overcome the fact that it doesn't inherit from
TreeWalker.
