ok...It turns out I can answer my own question!a blog post by Brian
Carper [1] cleared it out for me...I am looking for a *custom literal* -
not a tagged literal and for that one has to patch the reader which I'm
sure is *not* a good idea! anyway it seems I 've misunderstood certain
things
Greetings and all best wishes for 2013 to everyone!!! :-)
First of all, forgive me for hijacking this thread but I what I started
to do originated from this thread and so I feel it is related.
So, for the fun (and the learning) of it, I thought to create a queue
literal myself as suggested in
Hi,
I've reworked my tuple type into an ArrayVector type. Instead of using #[]
reader macro, ArrayVector replaces PersistentVector for small vectors and
falls back to PersistentVector as it grows. Fast destructuring is achieved
with ^ArrayVector hint.
See http://dev.clojure.org/jira/browse/CLJ
One idea is to reserve #[] for a concept that supersedes macros.
For instance, we have yet to apply the concept of protocols to macros.
Another direction is recursive subexpansion, a la mathematica.
If you consider transformations between code and data, there are 4
possibilities:
data->data (thi
Yes I have patched destructuring, http://goo.gl/Xc23p , and I use #[] for
both tuple creation and destructuring, see example in my earlier message.
Type hinting could be a nicer solution, I've never thought of it. Will try.

Have you also patched the destructuring mechanism?

How does the re
Significant performance gain is achieved when destructuring by skipping nth
and directly calling type fields instead. Concrete vector implementation is
not known when destructuring, so I'm left with a custom reader literal.
I seldom use queues but they seem like a good fit for a #[]

This is great! I will use it for my #[] reader literal.
Thank you,

You can also patch the LispReader in jvm Clojure without dropping to Java.
Here's an example of that to add a #b reader
literal:

Wouldn't it be better to implement this as an automatic optimization, just
like PersistentArrayMap vs PersistentHashMap ?
fwiw, I'm cautiously in favor of #[] being used for queues.

By patching LispReader in Clojure, http://goo.gl/tWnkq and ClojureScript
compiler http://goo.gl/nyKc5 . Used in closed source project, so I can use
my own flavor of Clojure there.

Jozef,
How do you achieve that?

I use it in Clojurescript for a custom tuple type.
For small number of items, deftypes are way faster to create and access
than PersistentVectors. I use tuple type e.g. for returning multiple values
from a function. Implementing #[] allowed me to have a compact syntax for
creating and destruct
I was just wondering - given that we have the #() and #{} literals, why not
a #[] as well? Queues look like a good fit.
