So the problem is that the Decompiler is not mapping the sequence pushLiteral: aBinding, send #value back into an appropriate LiteralVariableNode instance. The Decompiler needs to special-case this.

Isn't #value too general to serve as a specially treated token in the decompiler? It might easily appear in code.
I'd think it would be better if the compiler emitted a unique message selector that the decompiler could reliably recognize. Maybe #pvtValue, which cannot be used in regular code anyway?
