Whenever there is an external institutional stakeholder it is almost

I'd agree with this.
A closely held (financially) company with a small team of very bright

The reason is that I am reading in XML and mapping a tag name to the

I think I understand what you are saying.
So in practice you should prevent functions called from a macro from
evaluating the records (using quoting), so that the output is in a
form that looks like source code should?
So think it probably is my lack of intuition about macros that is the

Hello
Please could someone tell me the preferred way of attaching field
(key?) specific metadata in a defrecord definition?
And how to I extract this metadata on a field by field basis?

You can use recur to build a hierarchy. What do you mean by you can't
use it as it is not the last statement?
I have used recur in all sorts of places in the fn, without noticing
any restrictions, and built hierarchies.
I am no expert so I may have been conforming to the restrictions
accidentally
Useful, but not that sort of thing I'd ever think to look for unless I
had read about it.
Is there a wiki page somewhere that lists all this little libraries

Would be great to just read a list of ideas and check a few out that
hadn't thought about before.

One more Q.
What determines whether special forms can be used in functions eg you
can't def a variable in a fn.
Is it there some rule or is it special form specific depending on

I am not enough of a functional programming / Clojure expert to
comment on which library would integrate best with Clojure.
However I have always found iText to be badly designed (even though
historically it has been the mindshare leader with most features)
Also the licence on iText is GPL 3 with

removes duplicates)
Think my mind works in an obscure way, so prob not much use to anyone
else.

For clojure.test fixtures I understand you use :each for doing
