Attributes on primary constructors

[colejohnson66]

It is currently impossible to add attributes to a primary constructor:

[MyAttribute] // applies to entire class, not constructor
public class MyClass(int value)
{
    // ...
}

I propose [ctor: XAttribute] syntax, similar to [return: XAttribute] for method return values and [assembly: XAttribute] for assembly-level attributes.

It is currently impossible to add attributes to a primary constructor:

This is not the case. Roslyn, as an example, places attributes on primary constructors all over the place. You just need the [method: ...] syntax to specify this :)
