Phoenix is doing something that needs to be done and cannot be done any
other way. It is not the same with locals where there are other ways
to do the same thing and the only advantage I can see is a bit of
extra PP-based sugar. We can live without local functions, but we
cannot live without FP as a means for programming with anonymous
functions, lazy evaluation, partial function application, etc.

See the big difference?
