I was deliberately linking to the "very old" documentation,
because it has the property that (var1 var2 var3) is a valid
pattern matching a 3-element list. If I'm reading the newer
documentation right, it requires you to write (list var1 var2 var3),
which seems highly undesirable for a standard (built-in)
pattern language, and is incompatible with syntax-rules.
