I don't understand what you mean. As far as I can see, equations never 
look like classes in Python, regardless of whether you are using 
functional programming, object-oriented programming or procedural 
programming. Can you give me an example of what you mean?

Secondly, the proposal relates to *anonymous* functions, which is a 
small part of functional programming. Perhaps they are necessary in a 
purely functional programming language, but Python is not such a 
language. Python never *requires* anonymous functions, they are a 
convenience and that's all.
