Is there any way to iterate over the ChiselEnum enumeration names and values? Looking at the chipsalliance/chisel3#885 for the feature, MyEnum.Values was the proposed syntax for iterating over the values. However, this does not compile and I cannot find a definition for Value in the source either.

I'm using ChiselEnum to encode instruction types, and I'm now writing a module that would parse human readable ASCII strings from the different enumeration values.

This is some pseudocode for the approach I was thinking of:

def ascii_bits(message: String): Bits = ("h"+message.map(c => "%02x".format(c.toByte)).mkString).U

class DebugInstrText extends Module {
    val io = IO(new Bundle {
        val instr = Input(Instruction())
        val instr_text = Output(Bits(48.W))
    })

    io.instr_text := ascii_bits("xxxxxx")
    for (i <- Instruction.Values) {
        when (io.instr === i) {
            io.instr_text := ascii_bits(instr_names[i])  // instr_name is an array/map with the corresponding strings
        }
    }
}

I would appreciate any feedback about how to achieve this, or if there exist workarounds/better alternatives for achieving similar functionality.
