RFC: Namespacing (Zones) about arua-meta HOT 1 OPEN

Possible ways of going about namespacing in Arua could be using the C++ methodology.

In Arua of course the syntax would need to be modified slightly but the end result would be the same as a C++ namespace:

namespace stuff
{
    // All the code
}

# Arua example
ns {aruaNamespace}
    # Methods, structs, types, vars here
# namespace ends here at col:0

I'm thinking wrapping the namespace name inside curly braces would be easy to help the compiler deduce the name and index it. Of course another possible method would be:

ns aruaNamespace:
    # Methods, structs, types, vars here
# namespace ends here at col:0

Keeping the idea of simplicity? I'd go with example 2. Also using the ns keyword would be shorter than writing out namespace.

Including namespaces

I would love to see a Python-esque method of including the namespaces (note, defined as use).
Example (as seen in #16):

use std.math.ops.*

Another feature that would be nice to include with this would be how you can (in python) use:

import foo as bar

# Or importing a specific class from a file
from foo import doThings

You could possibly do this in Arua by doing:

# Importing the whole library
use std.math.ops.*

# Importing specific class or method
from std.math.ops use Fourier

# Aliasing the import
# Updated for an easier "Aliasing" system
# Could use "aliasas" but I find that's confusing and superflouous 
from std.math.ops.* use Fourier as Transforms
