Answer 1

I came across a situation need to check the parameter need to be certain type. Maybe can active a better way.

Like this:

@required [{"body", "binary"},{"fee", "integer"}, ...]
defp match_desire?({value, type}) do
  apply(Kernel, :"is_#{type}", [value])
end

Usage:

Enum.map(@required, &(match_desire?/1))
