Ruby has two kinds of functions. Methods are functions attached to objects. Lambdas are functions that are not. Ruby lambdas are exactly like javascript arrow functions, or python functions.

There's a _reason_ for the difference, since it determines the implicit self, which is a meaningful part of how Ruby works. Because that difference is meaningful it is reflected in the syntax. `lambda`, or the shorthand `->` creates a function not attached to an object, and `def` creates a function and attaches it to the calling context (making it a method).

Perhaps you don't like this, that's fine. But to say "nope I want my methods and functions to be interchangeable and not to be called lambdas" is purely a subjective argument.

Objectively, Ruby has first-class functions that can be assigned to variables and passes around and returned from other function calls etc etc. They're just called lambdas.
