It's a small thing, but all the other basic types have dedicated
predicates.
character-p-patch adds this.

Keywords are like symbols, except:
o They can and must begin with a colon, e.g. :fred.
o They cannot contain '.' or name classes.
The last requirement does not seem to be enforced by the reader:

Macros in closure are (fn ...) where the var in which the function
resides has a flag in the metadata set. Which means there is no
difference between the two except to eval (or apply).
I was just thinking that all of the def* should share return values.

The original and 'pure' notion of metadata was only for value types,
specifically:
(with-meta x new-meta)
should not affect x.
It's becoming obvious that metadata is d

I was thinking about the well known idea of connecting to a REPL in a
production system and fixing things on the fly without downtime. Rich
talks about this in his presentations.
I am kind of embarrassed to ask this, but is there a "correct way" to

I'm new to Lisp so please forgive me if I'm way off track here...
Macros are not functions, and don't enjoy the same rights as first
class functions (ie: being assignable).
Macro-expansion happens before exe
When I screw up a lazy-cons (which happens quite a lot to me),
my repl goes nuts and appears to corrupt the box it lives in. If I

It's unlikely to come up, but I noticed this:
