allMembers

[Manu]

So I do a lot of module scanning via allMembers, and I'm consistently
running into an awkward problem:

module test.blah;

static this()
{
  foreach(m; __traits(allMembers, test.module))
  {
    // m is a string, the only way I know to address the thing m references
is: mixin(m), and this can't be involved in virtually any complex
expressions...

    // I need to know if m is an interface, class or struct
    static if( is( mixin(m) == [interface/class/struct] ) )   // how can I
do this? I can't use mixin() here.


    // I have a scenario where I need to know if m is a function, and I
made it work using an ugly trick like this:
    static if( is( typeof( mixin( m ) ) ) ) // this works!
    {
      // here, I know that m is an instance of something, which means I can
alias it's typeof()
      alias typeof( mixin( m ) ) Type;

      // ... and life is good
      static if( is( Type == function ) )
      {
        ...
      }
    }

    // that construct doesn't work for definitions, like
interface/class/struct

  }
}

What can I do?
