+// zclsp --annotate writes the types the compiler can see into a program that
+// has none. this one has none: locals take the type of what they start as, a
+// parameter takes the type every call gives it, and a function the type of
+// what it returns. what it can't tell it leaves alone (twice is called with
+// a plain word, so its parameter stays), and the program still means the
+// same thing: tests/test.sh runs both and compares.
