Sure, but those weren't the claims. The claim was that the result of
an expression statement was automatically printed unless it was None.
`for i in range(10): i` _used_ to print 10 values _even when run from
a program_ instead of from a shell. I wasn't clear about that
distinction before.
From Misc/HISTORY:
"""
==> Release 1.0.2 (4 May 1994) <==
...
* The result of a statement-level expression is no longer printed,
except_ for expressions entered interactively. Consequently, the -k
command line option is gone.
"""
Going back more:
"""
==> Release 0.9.9 (29 Jul 1993) <==
...
* New option -k raises an exception when an expression statement
yields a value other than None.
"""
Now I even recall the name of the early method-chaining user whose
complaints triggered those changes - but will let the past rest in
peace ;-)
> The only thing I'm only 90% sure of is whether the REPL always ignored None values.
I'm sure of that: it never showed None values. Because, if it had, I
would have remembered bitching about the endless annoyance ;-)
