	Don't these things belong to a macro layer? I mean a LISP-like macros, 
not C macros.

	In my other message I mentioned Nemerle 
http://nemerle.org/What_is_Nemerle . They talk about their macro support 
here http://nemerle.org/Macros

	I think Paul Graham has a series of essays on the advantages of macros 
in LISP etc http://www.paulgraham.com/avg.html

	Is there any text explaining what D templates can do versus macros as 
in LISP? That might be an interesting article to read...

	Thanks,
