Throwing object is a serious problem:
Assuming some code throws a 'FooBar'
There are a few options:
- return a pointer to it: but its unclear how long this will last for.
- return a copy of it: but not all objects are copyable
	(see exception_partial_info in the test suite for a case where you cannot do this)
- convert to a string & throw that
	it's not so useful, but it works (this is more lua like).
The third option (though not nice) is used
For a more useful solution: see std_except for more details
