Tuple Literals for parameter defaults

[KathleenDollard]

This issue came up in VBLang. It seems like an interesting idea, so I wanted it to appear here as well (since we'd do it both languages, if we did it).

Would that necessarily be true? C# doesn't support DateTime defaults, for example.

How would this be encoded? Multiple attributes? What would their values be? What about types that VB.NET allows to be defaulted but C# does not, like DateTime?

@HaloFour C# gives no special meaning to the type DateTime, while VB does. That is why they handle them differently. But both language recognize tuple types as special, which is why any additional support for them is likely to show up in both languages.

Definitely. And I'm not arguing against doing that.

I'm still curious about implementation ideas and what will happen when VB.NET declares a method with an optional/default tuple parameter with Dates. 😉
