Support dynamic importing semantics

[thisrabbit]

Background

Apart from the import statement, Python spec additional supports the dynamic importing semantics, which is as the form of function calls. Though the function accepts strings as parameters, which can be runtime generated, some simple circumstances should be analyzed since it is totally feasible.

Example

# foo.py
def foo():
  pass

# bar.py
import importlib  # The necessary built-in lib importing

obj = importlib.import_module('foo')  # Function call to specific semantic

obj.foo()  # Imported object can be accessed as any regular object

Status

Currently, neither ENRE nor Understand supports extraction of this.

Notice

The previous example only demonstrates one case of the function import_module, and still more usages are listed in the official spec. While implementing this, please do perform comprehensive investigations and fulfill all benchmarks.
