+// Torture test for weakrefs.  The first letter of an identifier
+// indicates whether/how it is defined; the second letter indicates
+// whether it is part of a variable or function test; the number that
+// follows is a test counter, and a letter that may follow enables
+// multiple identifiers within the same test (e.g., multiple weakrefs
+// or pointers to the same identifier).
+
+// Identifiers starting with W are weakrefs; those with p are
+// pointers; those with g are global definitions; those with l are
+// local definitions; those with w are expected to be weak undefined
+// in the symbol table; those with u are expected to be marked as
+// non-weak undefined in the symbol table.
