What's wrong with using a nested named functions instead?

You may already be aware, but not everyone is: they capture variables from outer scopes in exactly the same way that lambdas do.

It's wrong because naming is hard. When writing inline, it is possible that not having a name does not impact readability. When defining the function out of line, naming it casually may confuse readers.

When we use lambdas, don't we usual end up assigning them to variables? In those cases, your point about naming will still hold!

Lambdas are assigned to function arguments/parameters. Pretty sure assigning a lambda to a variable is an anti-pattern.

It's just more pleasant to be able to write anonymous functions and to be able to extend them past a single line. If I had to name all of my anonymous functions that I write in other languages, I'd find another way to accomplish what I was trying to do with them.
