org.apache.flex.compiler.internal.as.codegen.InstructionListNode
A node to use to inject an InstructionList in places that an Expression is expected. This is for use when the compiler can easily synthesize an instruction list for some boiler-plate code gen. This lets us avoid having to construct a Synthesized AST that would then be run through the code generator to produce the InstructionList. This also means that no semantic checking of the code in the InstructionList will be done. If you are using this, then it is assumed you know what you are doing, and that you are putting correct code into the InstructionList
