[Swift-devel] globally readable variables

[Ben Clifford]

It seems desirable to make some kind of global variable in SwiftScript. I 
will not repeat the arguments here.

There seem two obvious syntax choices:

i) all top level variables become readable at all scopes.

ii) top level variables may be annotated with a "global" modifier to make 
them accessible at all scopes; otherwise they are accessible only in the 
same places they presently are accessible, the top level scope and its 
subscopes.

I'm aware of a preference from one person for i) and a slight preference 
from another for ii) - does anyone have partcular thoughts?
