…thanks. I already guessed it wasn’t that easy ;) I’ve added it to [1].
In general, I hope we could get completely rid of self-dependency checks. It was only defined for variables, not for functions, and I cannot see why we still need it today. We are currently discussing this topic for version 4.0 [2].
Best, Christian

Christian, thanks very much.
I returned to my actual code, and it works with the latest snapshot dated today.
By the way, I also retried the variations I had created when trying to explore workarounds, and one of them still doesn't work with the latest snapshot. It's not blocking me, but in case it is helpful, I reduced it to another small query that reproduces the error with today's snapshot. I know you said you fixed part of the problem, so you might not be surprised that the following code still triggers the error.
xquery version "3.1";
declare variable $variant := if (exists(function-lookup(QName('nonexistent','nonexistent'), 0))) then ( (: not relevant :) ) else function-lookup(QName('http://www.w3.org/2005/xpath-functions%27,%27string'), 1);
declare variable $variant-fcns := $variant;
declare function local:fcn() { $variant-fcns('abc') };
local:fcn()
The levels of indirection (variable, variable, function, function call) seem to be relevant for the problem. If I make the code more direct, it works.
Regards, Amanda

Hi, all.
I'm seeing an error in BaseX when I use function-lookup in both a global variable and a function, where the function relies on the variable. I reduced the situation to the following small query:
xquery version "3.1"; declare variable $local:lookup := function-lookup(QName("nonexistent", "nonexistent"), 1); declare function local:myfcn() { let $f := ($local:lookup, function-lookup(QName(' http://www.w3.org/2005/xpath-functions%27,%27string'), 1))[1] return $f('a') }; local:myfcn()
When I run it with BaseX 11.1, I get [XQDY0054] Static variable depends on itself: $local:lookup
When I run it with Saxon-HE 12, I don't get this error.
Is there anything I can do in my code to avoid this error?
Thanks, Amanda
