Right now we don't. I see that some JetStream subtest runs into this.

(In reply to Saam Barati from comment #0) > Right now we don't. I see that some JetStream subtest runs into this. Actually, we can see bunch of giving up FTL compilation in web-tooling-benchmark due to the lack of ArrayStorage support in operations (PutByVal etc.). Now FTL can compile even an Eval node. FTL coverage should be expanded :)
