Because every camel has its straw, I need to agree here. I, and most
of my python buddies, fight with bloodstained teeth and nails to get
python in our projects and developments. I can't see winning too many
arguments when my opposition can pull out 'the division operator' to
shoot me down. I can't see budgeting time and people to making sure
the division operator works after an upgrade. I'd be laughed into data
Options such as // for the new semantics, keeping / as integer div
seem quite reasonable. Or even allowing / to be used with the new
semantics given some "from __something__ import something" seems very
acceptable. And not just as a stepping stone to future versions, as a
permanent change to how the interpreter works.
Reading the points people make keeps reminding me of a joke.
A Mathematician, an Engineer and a Physicist are hunting in the woods.
The come upon a trophy buck. The Physicist shoots and the shot is 5
feet too low. He mumbles about improper air resistance and drag.
The engineer then fires and the shot is 5 feet too high. He mumbles
about overcompensating for environmental variables.
The mathematician looks left at the Physicist, right at the Engineer
and exclaims, "You got him!"
