Hmmmmmm.  That I ever wrote a syntax-rules tutorial, except twice in
haste at the spur of the moment on IRC, is indeed surprising news to
me.

Perhaps you may be thinking of Joe Marshall's tutorial, which describes
the MACRO-CALL & ! token technique.  Although the thought of that
technique did occur to me long before JRM's tutorial was written (or at
least released -- if my memory serves me chronologically correctly), I
never mentioned it to anyone except perhaps Matthias Radestock, so
still no credit would be due to me.
