is there a way to determine on what file and line number an error has occurred that was tried-and-caught?

(I don’t think a println(stacktrace()) gives me this, at least not in a way that I can recognize it. At the time of a stacktrace() in the catch, it’s already unwound the stack.)

Use `catch_stacktrace()` in your `catch` block instead (or `stacktrace(catch_backtrace())` on 0.7). See [here](https://docs.julialang.org/en/latest/manual/stacktraces/#Error-handling-1) for the relevant docs.
