In my implementation of syntax-rules/syntax-case, I did essentially
the same thing as syntax-quote (had to reimplement it as there is no

You can write anaphora with syntax-case. In fact, defmacro i

That's only true for syntax-rules macros. syntax-case macros, which
most schemes provide and are required by R6RS, are, strictly sp
You might be interested in the paper 'Fortifying Macros':
http://www.ccs.neu.edu/scheme/pubs/icfp10-cf.pdf syntax-parse is very
cool and can give good error messages if the user makes a mistake when
using the macro. About a year ago I tried making an implementation of
a system like syntax-parse f

This talk of "Scheme macros" is a little weird: are we talking syntax-case,
explicit-renaming, or unhygienic defmacro? Scheme has them all.
There are also implementation-specific mechanisms for writing reader macros:
what's left?

Let over Lambda is essentially a huge essay about why there's and will
never be anything as powerful than the CL macro system.

I think that Common Lisp macros are, strictly speaking, more powerful than

Hi everyone,
I was searching the web these days trying to find out more about these
two macro systems and understand their differences, and why one is
preferable over the other (or not). I'd like to share with you some
