I would like to know if (and how) one can create macros that would be similar
to `suite` template from `unittest`. I.e. with a "head" on the same line that
the name of macro and a body after a colon. What I would like to parse is
something like this:
model "Person":
field Name(string):
max_length = 128
field Age(int):
unsigned
validate Age > 20
I tried several signatures for my macro, to no avail. With `macro model(name:
string, body: untyped): untyped` I get only the string "Person" under `body`.
Other signatures fail saying `Error: type mismatch: got (string, void)` ``
So can I do it or do I need to change the semantics here?
