Paul Backus <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #1 from Paul Backus <[email protected]> --- The first example looks like a bad error message. The actual problem is that you cannot call a @system copy constructor from @safe code--and indeed, changing main to @system allows the example to compile successfully. The second example is a mistake in SumType, and should not be difficult to fix. --
