[Tutor] Syntax Check

[Chad Crabtree]

Well I don't think that it would really require that.  I could just 
define macro's in a module and just do it like so

import macro
import defined_macros as m
macro.expand(m.with(),m.assert()) 

I just thought it would be best to have definitions at the head of a 
script, or at least to have the option.
