[Tutor] Syntax Check

[Chad Crabtree]

Ok I'll explain what I've done so far.  I'm using tokenize to take
the 
file that imports macro; found by using  stack inspection and then 
tokenize it.  I look at all the string tokens to see if they match
they 
pattern a macro should have.  Then I pass the macro string through
the 
tokenizer again to expand this and to maintain the indentation needed

for the block.  I did this as an exercise and I thought the 'with' 
extension would be nice for my own benefit.  I thought it would be 
useful for all those syntax propositions in PEPs and stuff to
actually 
implement them to see how they work in real life.  However in it's 
current state I have to use anonymous ('''****''') strings to
surround 
the macro.  I just thought it would be nice to just have python
import 
macro run the first few things with out looking to far into the file,
at 
which point macro.expand() would take over.

Now that you mention it and I'm thinking about it, it would probably 
take some sort of MacroPython->Python compiler type thing.  To get
the 
feel I'm really looking for.  I guess I was thinking it would work
like 
psyco

import psyco
psyco.full()

I hope I made myself clearer.
