a couple:
the "log" library has an [error] object, which does exactly this.

i find this a bit inconvenient because the "find last error" will get
you to the [error] object itself, rather than to the object that
actually threw the error (the abstraction wherein the [error] was
generated).

therefore, iemguts' [canvaserror] will mark an upstream canvas as the
trackable object, so the user is lead to the (imo) "correct" object.
