Thank you.

Consensus in the Working Group is that they, and the phasing problems
they introduce, were unsuitable for the small language.  With just
syntax-rules, we didn't have to worry about the issues of executing
Scheme code at compile time (that is, macro expansion time).

They will be present in the large language, at least in the form of
explicit-renaming macros.  Syntactic closures and syntax-rules are also
possibilities.
