The Python That Wasn't
Presented by Larry Hastings
One reason for Python's success is its restraint in adding new language features. Only the most essential changes make it--and for every change that gets accepted, many more are rejected. Come learn about proposed changes to the Python language that failed--what, how, and why.
- Quick overview of the process
- First ten years: send GvR a patch
- The modern approach: python-ideas, write a PEP, produce a reference implementation
- Discuss the "prickly" Python community
- This is a good thing! Only the best ideas survive the python-dev gauntlet!
- They do this not because they're mean, but because they care so much.
- We must have eternal vigilance to prevent unnecessary changes!
- A survey of some changes that didn't make it
- The switch/case statement (PEP 3103)
- The "freeze protocol" (PEP 351)
- The "dynamic attribute access" proposal from python-dev, 2007/02
- Many more possibilities await in the rejected PEPs!
- My message to the audience
- Start with a post to python-ideas, please!
- Don't be surprised if you get a negative reaction
- Don't let your fear of a negative reaction stop you from trying, necessarily
- Do your homework, and be your own worst critic
