> lambdas having pretty wild constraints (only one line??)

I will never understand why people are upset about this.

You HAVE multi-line lambdas. They're called functions.

Yeah, I know you want a function that's only used once to be able to be defined in-line, but tbh I've always found that syntax to be pretty ugly, especially once you're passing two functions to a single call, or have additional parameters AFTER the function (I'm looking at you, setTimeout/setInterval).

Except of course for those that did, Haskell, Fortran for example.

F# as well, and that tends to exist in parallel with some degree of C# written by the same devs… the indentation enables cleaner, smaller, simpler code function by function.

It’s pretty ok in Python, but meaningful indentation is amazing with a proper type system and compiler. Clean, consistent, efficient, and ensures working code is easily read and standardized.

I’m unaware of anyone accepting improperly formatted C# as ‘done’, and would reject any such PR out of hand because of the potential for legibility issues to hide bugs. So: if it were done when 'tis done, then 'twere well it were done by the compiler to save line noise.

I’m always baffled when language complaints come down to syntax

That’s exactly how I think, too. But at the same time, I like indentation in Python, because I would logically indent in every other language as well. In fact, I find all those semicolons and similar things at the end of each line completely redundant (why should I repeat myself for something the compiler should do) and I hate them. And that’s despite having experience with Modula and 10 years of C++. But when I look at Rust, I find the syntax simply awful. From an ADHD perspective…

Lambdas are intentionally kneecapped in python because Guido van Robson doesn't want to make a functional language. (As in "functional programming", not that it doesn't work.)

Guido van Rossum didn't oppose functional programming, but he wanted to keep the language (and the interpreter) simple.

"I didn't envision Python as a functional language" https://python-history.blogspot.com/2009/04/origins-of-pytho...

"I don't think it makes much sense to try to add "functional" primitives to Python, because the reason those primitives work well in functional languages don't apply to Python, and they make the code pretty unreadable for people who aren't used to functional languages (which means most programmers). I also don't think that the current crop of functional languages is ready for mainstream." https://developers.slashdot.org/story/13/08/25/2115204/inter...
