Bug when using $unsigned in ?:

[b1f6c1c4]

Input:

module M(input c);
  logic [31:0] w0 = c ? '0 : $unsigned(0);
  logic [31:0] w1 = c ? '0 : unsigned'(0);
endmodule

Output from sv2v v0.0.4 (cc9f7f4):

module M (c);
    input c;
    wire [31:0] w0 = (c ? $bits(type($unsigned))'(1'sb0) : $unsigned(0));
    wire [31:0] w1 = (c ? $bits(type($unsigned))'(1'sb0) : $unsigned(0));
endmodule
