Example 1 with X

use of ast.Expression.X in project L42 by ElvisResearchGroup.

the class Desugar method visit1Step.

    //we can assumethe receivers are normalized after DesugarContext
    //assert s.getReceiver() instanceof Ast.Atom:      s.getReceiver();
    //but nor really, since vars accesses are replaced by meth calls. In that case is fine to not have an atom.
    //(b=r.builder() b.a() b.b() b.c() .... b)
