I fully agree with that, the way I would handle that is with some macros to
generate the conversion functions:
statuses = [draft: 0, pending: 1, complete: 2, published: 3]
for {atom, int} <- statuses do
def to_status(unquote(int)), do: unquote(atom)
def from_status(unquote(atom)), do: unquote(int)
end
This gives you two functions and no free-floating magic numbers.
