On a certain database, the evaluator was spending 17 seconds on a single
iteration, which is usually a bad sign.
Looking more closely, we find the following culprit:
```
(621s) Tuple counts for PoorMansFunctionResolution::poorMansFunctionTracker/2#75430e01/3@i1#fb44303q after 17.8s:

278197 ~5% {3} r3 = r1 UNION r2
return r3
```
This is clearly silly. We're creating a type tracker start spot for
_every expression_, and only then filtering them down to just final
decorator calls.
To fix this, I simply pushed the `.asExpr` into `lastDecoratorCall` and
made that `pragma[nomagic]`.
This resulted in a much more reasonable iteration:
```

278197 ~5% {3} r3 = r1 UNION r2
return r3
```
That's better, but can we do better still? Ideally, we'll join with
`lastDecoratorCall` _first_, and only then consider `LocalSourceNode`s.
Time to add some pragmas:
```

Perfect! (Here, the optimiser has for some reason decided to inline
`t.start()`, but this is not important.)

Note the double evaluation again. This will need to be investigated
further.
The "most expensive predicates" report had the following line on a

Clearly, waiting to joining with `getModuleReference` last is not
healthy. To fix this, I opted to simply create a helper predicate for
the `accesses` construct.
After this change, here are the iteration timings
