Does Raven capture an exception whenever an Error object is instantiated?

In some of my Sentry entries, the line of code that is implicated looks to be the line where me Error object is instantiated, not where it is thrown.

Is that to be expected? It doesn’t seem right to me, since an Error is just a special type of object that is useful when it is thrown, not when it is created.

Did I miss something in the docs?
