*To me* you have this backwards.  The function-object creation code is 
executed *before* the call that passes that object.  This is true whether 
it is placed before, as above, or nested within, as you and Tomer prefer.

I (and many others, apparently) am less comfortable reading deeply nested 
code inside out than perhaps you and Tomer.  If a function body is more 
complicated than 'return <expression>', I prefer to have it factored out.

To both of us, but we differ at least slightly in what is most readable.
