The python/lua ones are great, but C++ ones I don't like

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
