Why are these things called 'anonymous functions'? That name connotes
lambda, which would create an unnamed function you could store in a
variable, pass as an argument, return from a function, and call at
some later time. They should be called 'local scopes' or 'local
blocks' or even 'blocks', and use their own reserved word.
The concepts are of course related; in lisp-like languages
(let ((a <e1>) (b <e2>) (c <e3>)) <body>)
is of course equivalent to
((lambda (a b c) <body>) <e1> <e2> <e3>)
