Well, the idea was to find a consensus. People obviously want to have
local functions. I was trying to find a solution that somehow get rid of
some of my objections, mainly verbosity of the local function
declarations. The complexity mainly comes due to the need to capture
variables in scope. By generating a local phoenix function, which can be
used in regular phoenix expressions, which can capture variables in
scope very natural (just pass them as function parameters). I am still
not happy that we need macros to declare (local) functions, but i guess
that is what it takes.
