Thank you Jaap!
The benefit of today's syntax is that the arguments are data, which makes
them easy to control and manipulate. Imagine you want to dynamically import
some data, how do you dynamically build a list or a tuple of {defrecord/2,
extract/2} entries?
The data syntax is also what you get back from all of the introspection
functions in Elixir, such as String.__info__(:functions). Also, today's
syntax support `:except` and other options, which are not considered in the
new syntax.
I would like to see those points considered before further considering a
new syntax.
