[Python-Dev] PEP 572: A backward step in readability
The PEP s section on Frequently raised objections includes:
> This could be used to create ugly code!
> So can anything else. This is a tool, and it is up to the programmer to use it where
> it makes sense, and not use it where superior constructs can be used.
The above is so dismissive of a very real problem.
* Python makes syntax decisions to make it easier to read.
* One of the first, and enduring ones was "No assignment within expressions".
* I had both seen, and debugged problems in the C-language caused by assignment
expressions; and was glad to be rid of them in Python.
Assignment within expressions was, I think, difficult to *teach* in
C. And will become
something error-prone to *learn* in Python.
The Python community has grown over the decades, and we have attracted community
members who want to help and are motivated, but Python is not a
tick-list of features.
A PEP that can detract from readability; *readability*, a central
tenet of Python, should
be rejected, (on principle!), when such objections are treated so dismissively.
