exalt

Python 3.7 Not production ready Travis status

exalt provides a convenient way to dynamically create closures and bind them to a custom namespace. This is primarily useful for preserving an execution-context when calling into a different function.

from exalt import promote
def baz():
 return bar
def foo():
 bar = "baz"
 return promote(baz, **locals())()
print(foo())

baz

pip3 install --user exalt

exalt heavily relies on CPython implementation details and probably shouldn't be used in a production environment.
