How to find nodes with a scalar predicate having values found during traversal

{ steve as var(func: allofterms(name@en, “Stesven”)) { director.film { fn as name@en } } stevens(func: uid(steve)) { director.film @filter(eq(name@en, val(fn))){ name@. } } }

If I place val() as first argument to eq() function it works great. Is there any reason it behaves this way? @MichelDiz
