log:collectAllIn error

[giacomociti]

Apparently, log:collectAllIn works only when the scope is the current document. The following example:

@prefix log: <http://www.w3.org/2000/10/swap/log#> .
@prefix : <http://example.org/> .

{ 
  (?x { ?x a :Test } ?xs) log:collectAllIn { :x a :Test } 
} 
=> 
{
  ?xs a :Result
}.

gives the error:

Error: Error while executing query: Foreign predicate shell/2 did not clear exception: error(system_error,context(shell/2,Function not implemented))
** ERROR ** eam ** error(existence_error(source_sink,/tmp/swipl_eye_42_4),context(system:open/4,No such file or directory))

The native eye returns (:x) a :Result.

The graph literal scoped log:collectAllIn is implemented via invoking another reasoner run using shell/2 which is not implemented in the swipl wasm version.
