from memory, they're implemented by using a "dup" bytecode and then 
"expanding"

    a := b

    bytecodes for a
    bytecodes for b
    bytecode for assign

    a ||:= b

    bytecodes for a
    dup
    bytecodes for b
    bytecode for ||
    bytecode for assign

so technically, the runtime doesn't know about assignment ops.

could be wrong though...
