I have the opposite opinion, having written Python for many years. Dynamic typing is almost never better or necessary, but significant whitespace makes for excellent syntax with no downsides.
It might not be a highly visible downside, but it's there nonetheless. It's better to be honest about that than pretend there is no cultural tradeoff that comes with making such a (IMO) terrible design decision in a language.
There are plenty of people that feel the same way about sigils (like `$foo` in Perl) and semi-colons. I've never understood it -- and likely never will, at this point -- but I don't pretend that there isn't a real demographic effect that these choices bring with them.
Biggest downside: copying and pasting code breaks in a lot of apps.
Jira, Teams, and probably some others, eat whitespace for breakfast. So if a coworker gives me a code snippet they have to manually edit it (often not even possible) OR I have to, or it won't even run. And since the whitespace is significant, it can't be auto formatted.
Whereas with C# you can copy the most fucked up snippet, put it in your editor and boom - auto-formatted and compiles.
Python’s grammar works great for expressions-inside-statements (and expressions-inside-expressions), but it can’t do statements-inside-expressions. Every attempt to support the latter turns out really ugly, at least in corner cases.
That said, I totally agree that full anonymous functions would be useful (especially for more complex logic). Might explore adding those later, but I love the message the current model sends.
