Mark,
Yes, I think so. My understanding of a reader marco is a character or set
of characters that is a shortcut for some other special form/macro that you
could use if the reader macro didn't exist. By that definition, I think
[...] and {...} are also reader macros. I think \ just part of the literal
syntax of a character, much like how 4 is part of the literal syntax of 42.
I think "" for a string is similar, which also makes it not a reader macro.
The comma is just simply another whitespace character, like space, tab or
newline, so again, that's not a reader macro. It's just part of the syntax
the reader uses. In the case of & in an argument list, I believe that is
just a symbol that the let special form uses for special meaning, just like
:as and :keys are special meaning when used within a let binding.
