Hi Christian,
This is great. I particularly like the way errors in the async execution are captured:
declare function local:result($id){ try{ map{ "result":async:result($id) } } catch * { map{ "error": map { 'code': $err:code, 'description': $err:description, 'module': $err:module, 'line': $err:line-number, 'column': $err:column-number, 'value': $err:value } } } }; async:ids()!local:result(.)
I see async:update is marked as an updating function.Is this correct as it also returns a result? I would have thought it causes an update later but it is not itself updating. This causes problems as the query id can not be captured or suppressed from the output.

Hi everyone,
As some of you know, James Wright has presented his excellent work on the Promise Module in Prague [1,2].
The promise:fork-join function is now part of BaseX, along with some additional functions for asynchronous query processing [3,4].
Your feedback is welcome as usual, Christian
