A tiny proposal: extend namespace grammar for more convenience.

[germa...@gmail.com]

Hello,

Rationale: Using nested namespaces with the need to open several sets of brackets just contributes to more

noise without any gain. Sometimes we just want to open a namespace to add functions/classes, etc that

are nested in two or three namespaces, like this:

namespace hello {

namespace my {

namespace world {

}

}

}

In C# you can write:

namespace Hello.My.World {

}

I think it would be a natural extension to allow:

namespace hello::my::world {

}

to be the exact equivalent of

namespace hello {

namespace my {

namespace world {

}

}

}

This would elminate some annoying bracket matching and I don't think

(I am no expert) that its implementation would be difficult.

As in C#, no namespace needs to exist previously to use that syntax.
