Module (namespace)

Users may add more and more scripting interfaces to MY-BASIC, it will soon cause a naming pollution issue. It's able to separate scripting interfaces to different modules (refers to "namespace" in some other programming languages).

Use mb_begin_module to begin a module with a module name, all functions registered after a module began will be put in that module; use mb_end_module to end the current module. See the sample below:

mb_begin_module(s, "naming");

mb_register_func(s, "foo", _foo); // Register "foo" in module "naming"

mb_end_module(s);

After that it's able to write naming.foo() to call the interface.

Use IMPORT @xxx to import a module, and all symbols in that module could be used without the module prefix. Eg. after import "@naming", it's able to use foo() for short.
