Does anyone have an unambiguous reference to a passage that claims
that the syntax ``:1'' denotes a symbol? In the 3600 implementation,
it's a number and I've heard people claim that this is a bug, but
I just looked and could not find any text which convinced me of this.
If no one can convince me, I'll write up a cleanup item.
See pages 343-344:
"If there is a single package marker, and it occurs at the beginning of the
token, then the token is interpreted as a keyword, that is, a symbol in the
:keyword package. The part of the token after the package marker must not
have the syntax of a number."
[Unfortunately this leaves the question of potential numbers vague at best.]
"All other patterns of package markers ... presently do not mean anything
in Common Lisp.... It is therefore an error to use such patterns in a
Common Lisp program. The valid patterns for tokens may be summarized as
where nnnnn has the syntax of a number, and xxxxx and ppppp do not have the
syntax of a number."
So the token ":1" is an error and may be given any interpretation by
