From http://clojure.org/metadata:
Symbols and collections support metadata, a map of data about the
symbol or collection

I'm attempting to learn Clojure with a long history of OO and have some
questions.I've created a defstruct for a place type object like:
(defstruct place :id :name :street :city :state :zip)
I want to write a function that would take a list of places and remove
the duplicates. Duplicates ar
Hi Brian,
(1) What does it mean to be equal on id and not equal on the other
fields? If two fields claim the same id but a different name, how
would you know which one to keep?
(2) Given some answer to #1, why not store the structs in a map under
id?
(3) For the geocoded place struct, I w
This is a tangent from Brian's question about struct inheritance:
While I am not sure that I want struct inheritance, it seems
unnecessarily hard to write the macro for it. Structs are not first
class citizens, in that you cannot reflect against them. I want to ask:

How do you make a two-dimensional array of a given size? (e.g. (make-
array '(i j)) in common lisp)
I want to do stuff like, e.g., representing a chessboard, where I can
index into cells and update them.

This destructuring on sequences works:

Is it bad etiquette to reply to myself? I thought it might be useful
to compare the proposed syntax with that of other languages with good

I tried all the examples from my previous message in Perl, Python,

Hello Rich,
in the definition of isa? in boot.clj in the last line (no. 2879),
there isa? recurs into the contents of the vectors. It uses
implicitely the global-hierarchy instead of the provided
one.
Shouldn't it be
(isa? h (child i) (parent i))
instead of
(isa? (child i) (parent i))
