property Pool<T> { ... }, function first<T>(xs: []T) -> T, map<T, U> over fn
types; a type writes an instance as Pool<Thing>, nested as deep as needed. The
parser names an instance Pool$Thing and remembers its generic and arguments; the
checker takes the generic declarations out, infers a call's type arguments from
its arguments or its result's declared slot, and makes each instance once as an
ordinary record or function, checked like any other. Errors print Pool<Thing>.
An instance keeps its generic's module and export (L3). ludic-fmt keeps type
arguments together while spacing comparisons and shifts.
