[TASK] Add balance_change array to transaction response, computed from metadata

I think we are arguing a consistency in style issue here, since semicolons are not required to terminate function declarations. (Again, I believe they are not inserted by ASI, either).

It does not. The spec does not require it, and implementations (V8) do not depend on it.

JSHint makes it difficult to specifically ignore semicolons at the end of function declarations, which is probably an indication that this style is rare (assumption).
