Access the global variable defined in other modules

Feature request

The JIT function can access the global variables defined in the current module, and functions defined in other modules. However, when trying to access global variables defined in other modules using module_name.variable_name, there is a compiling error.

'NoneType' object has no attribute 'module'

I find using

from module_name import variable_name

can make it work. However, using module_name.variable_name does not work.
