agents seem to mess up dynamic vars when run on a synchronous executor (send-via (reify Executor (execute [_ r] (.run ^Runnable r))) (agent nil) identity)

is it bug or feature ?

it seems intentional from the source (it uses binding-conveyor-fn which only works on separate threads)

and with agents being asynchronous, trying to use them synchronously doesn't seem to be a good idea

the idea doesn't sound that bad to me, sometimes you know the transformation is lightweight so you may want to avoid the price of a thread switch

after all, synchronous is just a special case of asynchronous

but maybe agents were not designed for that case
