Yes.  I’d like to try this with templates, when we get them, since
templates are supposed to share metadata with their species.

E.g., for a lambda form of a predefined shape with 2 free variables
(a type and a MH), define it as a template with those parameters
and inject it as many times as you see distinct combinations of
those parameters.
