The most obvious difference between racket's xexpr and yours is the '@' as

When loading modules I sometimes get syntax errors - rightfully so.
However, the errors sometimes don't have line numbers, making them time
consuming to find.
Here is one today:

I have the following error for a variable name that is used often in a
large file, Is there a way to coerce racket into telling me a function
name or line number?

According to the manual,
http://docs.racket-lang.org/db/query-api.html#%28part._transactions%29,
section
3.5, postgres transactions can be issued directly in SQL (so called
'unmanaged'). Here is a short code segment that fails doing unmanaged
transactions (and nothing else).

Saw this in another thread here, but the proposed solution didnt work, well
at least the way I understood it. So ..
In file db-lib.rkt I have a definition:
(provide db-exec)
(define (db-exec a) ...)
Then in racket
> (enter! "db-user.rkt")
Where db-citation.rkt has
(require "db-lib.rkt")
thank you! .. of course that makes sense. I guess that gensym and
uninterned symbols have something to do with this?
The identifiers in the macro are 'interned' (is that the terminology?
rather than renamed?) so in fact table-auth was never defined. Then at run
time there are complaints as such
oops sorry Daniel, I already put it over on the developers list.
The question is about the context and place of evaluation for
'table-author' and when it caused an error. Tha question never got
addressed here. However we did have a lot of "user" type answers.. seems
it belongs on the developers
I reformulated/clarified the question and bumped it over to the developers,
you can find it there. Thanks for helping with this.

Matthias thank you for fielding my question, though two things are not
clear. I hope you or someone might clarify.
Firstly, is there a reason to prefer the macro you present over the first
one given in the original post. I believe they both work. Neither uses
the more elegant syntax-rule.
