Well, it would break all the code of people who like to
write code that way. They might get a bit miffed if we
decide that their code is not serious. :-)

Thank you for your workarounds, Mark Bourne.
`metavar` argument should be sufficient for infrequent use scenarios, and I
will consider to use the custom help formatter if necessary.

Thomas,

Hen or Hanna,
You keep asking WHY which may be reasonable but hard or irrelevant in many
cases.
I find the traceback perfectly informative.
It says you asked it to print NOT just "a" but "a + 12" and the error is
coming not from PRINT but from trying to invoke addition between two objects

Adding to this, there should be no reason now in recent versions of
Python to ever use line continuation. Black goes so far as to state
"backslashes are bad and should never be used":

Does Python have an instrospection facility that can

bound, e.g.:

I found myself building a complicated logical condition with many ands and ors
which I made more manageable by putting the various terms on individual lines
and breaking them with the "\" line continuation character. In this context it
would have been nice to be able to add comments to lines terms
hello everyone:
I upgrade my project from Py3.10.4 to Py3.11.1 recently and I noticed Py3.11.1
is faster than Py3.10.4 except for some testcase, like __getattr__.
This is my test code in python discussion:
