This instruction duplicates the value at the op of the stack and inserts it 2 positions down so for example this stack
Top | |
A | B |
turns into
Top | | |
A | B | A |
maybe the duplicate instruction can have an optional number argument for where the duplicate goes. Default 0 puts it at the top (or right below the top value), 1 puts it below next value on the stack (basically matches the number of the java bytecode instruction) and any other value puts the duplicated value further down
