Just an FYI that I actually plan to try and make the activation scripts (at
least under PowerShell) completely static so they can be signed.

Currently EnvBuilder allows for a number of customizations of virtual
environments, changing which python is used, automatically installing
libraries, etc... However, it does not allow for any modifications of the
activate script itself (unless one wants to rewrite it completely).
However, a

Hi James
Something similar can already be done, say via
from somewhere import unittest
@unittest
def f():
# test code goes here
As it's your idea, I suggest you create and put up an implementation on
PyPi, and post again to this list when you have some real-world examples of
the use of this
I have been following this discussion for a long time, and coincidentally I
recently started working on a project that could make use of assignment
overloading. (As an aside it is a configuration system for a astronomical
data analysis pipeline that makes heavy use of descriptors to work around
# regular code
unittest:
# test code goes here
This code would be run when the runtime -unittest flag is passed. It would
function as test usages and example client code. The code within the block
would remain in .pyc, unless the -O switch is passed.

Yes, but it scales to speed, letting you speed up your code easily when you
need it. Consider Cython and Nuitka. Consider GraalPython. Consider... consider
that C dylibs can be loaded and used from within Python without any wrappers.
You can create the <-

The canonical example of a type as a collection of instances is an
enumeration, the simplest (useful) example of which is bool = {False,
True}.
In pre-big-integer Python, in principle you could do the same

Can we call it "party hat operator", please? <:-)

`<:` kind of notation would look more clear, I agree.
My proposition came after thinking the wording used in Python.
issubclass() - is subclass?
By definition, subclass reminds me set theory.

And what I'm asking for is a justification for that. Python in
general has done fine without it
