Of course. Hmmm. And I thought I knew this stuff! :)
I think I was getting all confused because I was playing with ns and
it doesn't require quoting (because it's a macro). It makes sense now

Hi guys,
I'm just wondering if it's possible for the following macro to be

What's supposed to do is take an arbitrary-form, and create a lazy
