I'm trying to stay out of FalconJS, but I will ask Bernd P about this.

Subject: RE: ABC -> JS

The JSEmitter is littered with the whole;

import org.apache.flex.abc.graph.IBasicBlock;
import org.apache.flex.abc.semantics.ClassInfo;
import org.apache.flex.abc.semantics.ExceptionInfo;
import org.apache.flex.abc.semantics.InstanceInfo;
import org.apache.flex.abc.semantics.Instruction;
import org.apache.flex.abc.semantics.Label;
import org.apache.flex.abc.semantics.Metadata;
import org.apache.flex.abc.semantics.MethodBodyInfo;
import org.apache.flex.abc.semantics.MethodInfo;
import org.apache.flex.abc.semantics.Name;
import org.apache.flex.abc.semantics.Namespace;
import org.apache.flex.abc.semantics.Nsset;
import org.apache.flex.abc.semantics.PooledValue;
import org.apache.flex.abc.semantics.ScriptInfo;
import org.apache.flex.abc.semantics.Trait;
import org.apache.flex.abc.semantics.Traits;
import org.apache.flex.abc.instructionlist.InstructionList;

He used the IABCVisitor which is all ABC as well.

Looking at this again, Alex put it well, it may be generating Strings but the WHOLE API of
the class is abc.semantics. If you don't know abc semantics, there is nothing you can do other
than learn it all.
