This is a nice way of putting things. There's a school of thought that says if things work how it says somewhere that they should work, then no part of the system is exhibiting a problem. But just in this thread we can see Python's insane treatment of default function parameters called a "bug in the language". I've long been mad about what I can only think of as a bug in the Java spec: bit shifts use the base-32 modulus of their actual operand. Sure, the specification says that that's what they're supposed to do, but when I ask the JVM to fill a 32-bit value with 40 zeroes from the right, I expect one of the only two sane results -- an exception or whatever value 32 zero bits represents. I'm pretty sure there is no circumstance where shifting in 8 zeroes could be correct or useful.

There's a lot of maintainers who seem convinced otherwise.

why is there anything in this thread besides your post is beyond me.
