I am disappointed that D doesn't have checked exceptions.
I wonder what could be done with something like this:
void foo(int a)
{
if (a > 0)
throw new BlahException("blah");
throw new BloopException("bloop");
}
unittest
{
// NEW FEATURE HERE
alias Exceptions = __traits(thrownTypes, foo);
}
I'm imagining one could use that to do quite a lot of what
checked exceptions provide.
Yes, that would be a D idiomatic implementation of the function
exception set I mentioned [1].
