The macros in my patch only accept one kind of arguments (expressions) ruling out several interesting usages. For instance, extending the syntax as in try {...} catch {...}. I actually consider that a plus. IMO, macros should be limited in both their power and scope. And the in-lining of 'functions' (only) is, for me, the perfect break point. The syntax and semantics of functions are very clearly defined and understood. And macros that mirror those are thus easy to learn reason about and use. It has been a very long time since I did Lisp, and I was not very good at it then; but I do remember that only thing worse than the (lack of) syntax, was the unholy mess you get into when trying to debug errant Lisp macros. Yuck! With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
