           Summary: Lazy parameter evaluation should be marked as nothrow
           Product: D
           Version: D2
          Hardware: All

This code should work, but doesn't.

void assertThrown(E)(lazy E expression)
{
    expression();
}

void main() nothrow
{
    assertThrown( 0 );
}


Currently lazy parameter evaluation `epxression()` is treated as @safe and
pure, but does not marked as nothrow. It's a bug.
