Generating type specs programmatically

[Viktor Söderqvist]

Hi! Generated examples of all of Erlang's AST is in the generated 
README.md of this repo:
https://github.com/zuiderkwast/erlang_abstract_format

Some examples:

-spec my_function() -> ok.

{attribute,54,spec,
            {{my_function,0},
             [{type,54,'fun',[{type,54,product,[]},{atom,54,ok}]}]}}

-spec my_function(A :: atom()) -> B when B :: boolean().

{attribute,55,spec,
     {{my_function,1},
      [{type,55,bounded_fun,
           [{type,55,'fun',
                [{type,55,product,
                     [{ann_type,55,[{var,55,'A'},{type,55,atom,[]}]}]},
                 {var,55,'B'}]},
            [{type,55,constraint,
                 [{atom,55,is_subtype},
                  [{var,55,'B'},{type,55,boolean,[]}]]}]]}]}}

If some syntactic element is missing, please let me know.

BRs,
Viktor
