-// So far instructions can only contain linear lists of properties. Now we add
-// support for more complex trees of properties in dilated reagents. This will
-// come in handy later for expressing complex types, like "a dictionary from
-// (address to array of charaters) to (list of numbers)".
-//
-// Type trees aren't as general as s-expressions even if they look like them:
-// the first element of a type tree is always an atom, and it can never be
-// dotted (right->right->right->...->right is always NULL).
-//
-// For now you can't use the simpler 'colon-based' representation inside type
-// trees. Once you start typing parens, keep on typing parens.
