TypeBuilder.GetProperties with flag doesn't work

[NN---]

namespace MacroLibrary1
{
  [MacroUsage(MacroPhase.WithTypedMembers, MacroTargets.Class)]
  public macro Macro1(tb : TypeBuilder)
  {
    M.Do(tb)
  }

  module M
  {
    public Do(tb : TypeBuilder) : PExpr
    {
      Message.Hint("Properties");
      foreach (v in tb.GetProperties())
        Message.Hint($"$v");

      Message.Hint("Instance properties");
      foreach (v in tb.GetProperties(BindingFlags.Instance))
        Message.Hint($"$v");

      Message.Hint("Static properties");
      foreach (v in tb.GetProperties(BindingFlags.Static))
        Message.Hint($"$v");
      <[ ]>
    }
  }
}

[Macro1]
class Program
{
  P : int { get { 0 } }
  static SP : int { get { 0 } }

  static Main() : void
  { }
}

Output

hint: Properties
hint: property: Program.SP : int { get; }
hint: property: Program.P : int { get; }
hint: Instance properties
hint: Static properties

No instance and static properties !

Workaround: specify "BindingFlags.Public | BindingFlags.NonPublic"

I think, you should add BindingFlags.Public or/and BindingFlags.NonPublic value.

Yes this helped.
But I think this should be implicit if you do not specify none of them.
