This is what you had in a prior iteration that does what you are describing.
```
profileConfig.getTickUpdate().forEach((var, expr) -> executor.assign(var,
expr, new HashMap<>()));
```
The only change that i suggested previously was to make the `result`
available to the `tick` expressions, which I think could be generally useful.
```
profileConfig.getTickUpdate().forEach((var, expr) -> executor.assign(var,
expr, Collections.singletonMap("result", result));
```
