Using declarations

A using declaration lets a file refer to visible declarations from another namespace by their short names:

namespace Application

using Geometry

function makeOrigin(): Point
    return origin()
end

using affects name resolution only. It does not load a file at runtime or execute initialization code.

Namespace aliases

Give a namespace a shorter or more distinctive local name with =:

namespace Application

using Geo = Company.Project.Geometry

function makeOrigin(): Geo.Point
    return Geo.origin()
end

An alias is especially helpful for long qualified names and collisions.

If multiple imported namespaces expose the same short name, Pop reports an ambiguity rather than silently choosing one. Resolve it by using a full qualified name or an alias.

Only declarations visible from the current Bubble can be reached through using; importing a namespace does not bypass private or internal access.
