The compiler could at some point recognize that the function is being
assigned to a simple name and transform the assignment into a def for
purposes of byte code generation. It could also do the same with
lambda, although it currently doesn't.

The reason I don't like this replacing def isn't because the name is
necessarily lost. It's because the lack of the well-defined def
statement encourages more complex usages like

    functions['f'] = x -> x**2

where such implicit transformations won't work.
