Chicken is not shut out.  It just means that WG2-conformant programs
have to use "er-macro-transformer" explicitly.  What happens if you
don't use an explicit transformer is outside the scope of the standard,
so Chicken can treat that as implicit ER and other implementations as
something else.

This is the advantage of standardizing a facade rather than what lies
beneath.

continent, a part of the main.  If a clod be washed away by the sea,
Europe is the less, as well as if a promontory were, as well as if a
manor of thy friends or of thine own were: any man's death diminishes me,
because I am involved in mankind, and therefore never send to know for
whom the bell tolls; it tolls for thee.  --John Donne
