Aklakan opened a new issue, #2896: URL: https://github.com/apache/jena/issues/2896
### Version 5.3.0-SNAPSHOT ### What happened? I am not sure whether this is according to [SEP7](https://github.com/w3c/sparql-dev/blob/main/SEP/SEP-0007/sep-0007.md) or a bug in Jena: I am trying to inject a value using lateral into a BIND in a subquery. The following works: ```sparql SELECT * { BIND('x' AS ?xIn) LATERAL { { SELECT * { BIND(?xIn AS ?xOut) } } } } ``` The result is: | ?xIn | ?xOut | |------|-------| | x | x | However, if in the lateral block there is a Join, then it breaks: ```sparql SELECT * { BIND('x' AS ?xIn) LATERAL { BIND("foo" AS ?foo) { SELECT * { BIND(?xIn AS ?xOut) } } } } ``` In the result, `?xOut` is (for me) unexpectedly unbound. | ?xIn | ?foo | ?xOut | |------|------|-------| | x | foo | | I think this is a bug in Jena (but perhaps I am misunderstanding something about the scoping rules). ### Relevant output and stacktrace _No response_ ### Are you interested in making a pull request?
