A friendly name for VecInit() in .sv?

[oharboe]

When I do this, in Chisel 7.0.0-RC3

  val countLength = VecInit(program.map(_(1)).map {
    case raw =>
       ... lots of chisel code
  })

I get:

        automatic logic [63:0][2:0] _GEN_4 =
          '{3'h0,
            3'h0,
            3'h0,

Use-case: I'm creating a "rom" in a testbench by using Chisel that evaluates to a VecInit(), I was surprised that I'm unable to get a friendly name in .sv. I tried countLength.suggestName("countLength").

I'm pleasantly shocked that this works, that it creates a ROM, as I'm Module(new Foo() with InlineInstance) for each element in the array above. Some serious constant folding going on.

It saves me a ton of work to be able to do these sort of constant expression ROMs for testbenches.
