I think by the time I was leaving grad school in '93 they were up to
R5RS already.

Interesting, the R3RS indeed has no date. The RRRS is dated 1985 and
the R4RS 1991. In think R3RS may have been 1986 or 1987. FWIW, I see
no date later than 1986 in the references. Then there was a long break
between R4 and R5. R5RS appeared in 1998.

I defer to your knowledge of the history.  8-)

I thought it was an R5 I was using because it had syntax-rules, but
re-reading the R_RS docs, I see that R4 could have had them as an
extension.
