Generic constructor with parameters fails to compile

The commented out line fails to compile. This bug has been in Silver for a while now.

Hi;

I’ve fixed the error (Unknown identifier T) but on .NET you can only instantiate T with zero parameters. (this is a platform limitation). So your workaround is probably the best way to go about it still.

Hey Carlo, it was already working if there were no parameters, even in old builds.

It’s too bad you cannot have your Silver compiler automatically generate the workaround code. When you say “this is a platform limitation” I assume there’s a good reason for you not to implement this now. But think about doing this later. A little polish goes a long way. Thanks.

Agreed. I’ll log an issue for future consideration.

Thank you Carlo. Good support for constructors is especially important in Swift especially because Swift pushes you to initialize all your non-optional variables in constructors. Cheers.
