`case while` evaluates the condition. If the condition's true it moves forward to the next line (i.e. into the body of the loop), but if it's false it moves forward several lines, until the line after the `end` statement. `case en

Does Nova include a JIT compiler? Or just an interpreter?

I think this is fine - I don't see why having the `end`s on separate lines would make it easier to understand: if ... if ... if ... if ... if ... x =

Nobody ever likes my suggestion to write them all on one line. I thought it was neat - the length of the word `end` makes it line up perfectly with 4-space indentation: class HtmlTransform class Code < Base def

I'm surprised by the complexity of Go's generic constraints, given the language's focus on simplicity. Things like the difference between "implementing" and "satisfying" a constraint [0], and exceptions ar

> You evaluate the innermost (i.e. the tail) expression first, and work your way out to the head. As a sexpr it is a little more obvious that way: `(= a (= b (= c 5)))` That's not true in Python though. a = b = c = <expre

Also, you can now use the same quote character that encloses an f-string within the {} expressions. That could make them harder to tokenize, because it makes it harder to recognise the end of the string.

That blog post seems a lot more involved - it adds code to the bytecode compiler as well as to the parser. I suspect that’s mostly because the `until` statement is more complex - but another factor seems to be Python’s change in parsing tec

In terms of “break everyone’s code for no good reason”, this proposal is comparable to the removal of the `print` statement.

To me, the proliferation of "better classes" implies there's a problem with Python's built-in classes - but what's wrong? Are they just too flexible and/or too verbose? Or actually deficient in some way?
