Review comment:
Can we consolidate known error codes into a class/enum with meaningful
variable names? I would like to be able to search for the error code in a known
location and understand what is going on when debugging in the future.
Similarly we should be able to search within the IDE which code paths can
possibly cause a given error code.

can be simplified
```
if (!canContinue(label)) {
break;

Review comment:
Seems like we ignore unknown variables. Shouldn't we fail fast when such
thing happens?

Review comment:
Shouldn't this be newInstance(). We create a new instance of HplClass,
we do not instantiate the HplClass.
