Well, whatever you're doing, you almost certainly shouldn't be catching Errors
(AssertErrors or otherwise). That's generally a very bad idea. Very little
cleanup is done when Errors are thrown. finally blocks get skipped. scope
statements get skipped. Destructors get skipped. Etc. So, once an Error is
thrown, it takes very little for the program to be in an invalid state.

hmm, docs say different things:

> If code detects an error like "out of memory," then an Error is thrown with a message saying "Out of memory". The function call stack is unwound, looking for a handler for the Error. Finally blocks are executed as the stack is unwound. If an error handler is found, execution resumes there. If not, the default Error handler is run, which displays the message and terminates the program.

Out of memory is somewhat special. It is supposed to be an Exception, but is an Error so that memory can be allocated in a nothrow function. It is also a much larger issue than most Exceptions as it can't be ignored like other exceptions.
