[Python-ideas] Towards harmony with JavaScript?

[Carl Smith]

Using lambdas doesn't solve the problem. I just kept the example short, but
had I used more than one expression in each function, you'd be back to
square one. You took advantage of the brevity of the example, but it's not
realistic.

There are lots of language specific features that library authors use, like
operator overloading, ABCs etc...

Python is a great language, and I always opt for it when it's an option,
but I've used it to write front-end code, and it sucks.
