Bug 10026 – Allow to assert that exception must be thrown

I'd like to suggest that existing syntax for assert() keyword was enhanced in order to allow detection of exception thrown by the expression provided. It may look like this: assert!(DivisionByZero)( powermod(2, 1000, 0) ); assert!(InvalidArgument)( fastsqrt(-42) ); (or it may look otherwise, I'm not really an expert in language syntax). The reason for such functionality to exist is that "assert" is used for unit-testing of a class or module. Correct handling of errors is part of the specification of any non-trivial class, and the "D way" to handle errors is by throwing exceptions. Which current assert cannot test. What do you think?

See: http://dlang.org/phobos/std_exception.html

Use assertThrown and assertNotThrown from std.exception.
