[plt-scheme] Macro practice

Todd, for the record, existing hygienic macro systems are MORE  
expressive than existing unhygienic macro systems. (I suspect that  
this could also be applied to theoretical models, but these models  
aren't complete enough to make this comparison meaningful.)

I urge you to start with a study of syntax-rules (a la TSPL or TYS)  
and then to proceed to syntax-case and friends. By that point Ryan  
will have finished his tutorial on syntax programming in PLT and  
you'll be in shape to increase your productivity by an order of  
magnitude. (Just as Paul Graham says)
