I had no idea that syntax existed, and find it completely at odds
with The Zen of Python. I'm torn between forgetting that I ever saw
it and using it for some evilly-obfuscated code.
When one collects snippets of Python code that are intended
to be inserted into programs, a snippet usually would have
to consist of two parts: One part to be inserted at the top
of the program, into the imports section, and then the actual
snippet.
This statement led inevitably to:
>>> sqrt = __import__("math").sqrt
>>> sqrt(4)
2.0

I don't know why; it just did.
"__import__" allows to write snippets that can be inserted
as they are without the need to do insertions at two different
places. (Possibly with a tool to later normalize the insertions
to the usual style.)
That's much too mature. Es ist Feierabend!
