It's fairly to see function calls as significant overhead. In fact, I
moved things *away* from a pure Vulcano style executor, and the benefits
weren't huge, primarily due to expression evaluation overhead (of which
function call overhead is one part). After JITing of expressions, it
becomes even more noticeable, because the overhead of the expression
evaluation is reduced.
I don't quite see why a Vulcano style executor should make function call
overhead meaningless?
