Sure, but there is a well known convention for such non-names already: meta
syntactical variables. In this case the name could be "foo" and all readers
will interpret this as "no name".
I admit to have wanted lambdas that are just as powerful as normal functions,
but often when I want it the code is nicer when a normal function is used.
