For almost all macros you'll probably ever define, you don't need to
drive macro expansion yourself.  You need it only if you have to
transform code that might be anywhere inside the macro's arguments,
possibly only created by nested macro calls, like !> and !< in case of
`go`.

I had a similar (but simpler) scenario once, where I had some macro
defining a rule in terms of a pattern and an action.  Such a rule could
be applied like a function, but it could also be applied as a test where
it wouldn't perform its action but just return a thunk encapsulating the
action.  But that encapsulation with a thunk cannot work if the action
uses `recur` to call the rule function recursively.  So in that case,
my macro had to replace recurs with normal recursive calls in the
"execute as test" case.
