The import construct makes all the members of the imported target available to the current module. So instead of writing:

one can write:

The target can be either a namespace or a type. When it's a type, all the type's static members can be referenced directly by name. So the previous example could be simplified even further:

The from clause can be used to specify an additional assembly reference as well as to disambiguate namespaces. When using a Namespace that is not defined in an assembly with the name of the Namespace, you should use from:

from also accepts a quoted string as argument for weird named assemblies:

And speaking of assembly references, the boo compiler automatically add 4 assembly references before compiling any code: Boo, Boo.Lang.Compiler, (ms)corlib and System.
