Cut paste from my own code base:

A few points. Do not give any value to the dynamic var, make it unbound and

One gotcha is that atoms add-watches do not always guarantee order

your atom operation is something like (swap! a inc), you may see values in

The way I'd do it is to write a function that caches the output writer or
stream. When the cache expires, the function closes the old writer and
opens a new one to the new file.
In the example below, I'm assuming you have a function that returns the
same name for the same hour.

@leon Thanks. I wish this were documented in the API for how to write
Clojure/Script compatible code. Just saw your answer on stackoverflow
If it were me, I'd put something like:
(def add-link* [my_id fname surname day2 month2 year2 hour2 min2 zone2])
inside the function that handles the route, hit the endpoint as you would,
and check that add-link* is receiving the arguments you expect.

Not sure if there's some other way, but that works fine. rlwrap has a lot

This is always tricky - the other dimension is that the transaction can span
multiple components which should all be ignorant of each other, so a collecting
