+# Slurp and Spew #
+
+The stdlib uses heap[1] to heap[15] as registers.
+
+The `slurpreg` and `spewreg` functions facilitate this by `spew`ing the stack
+onto the heap's pseudo-registers or `slurp`ing the pseudo-registers back to the
+stack. The functions preserve order in complementary fashion.
+
+The `spewreg` function uses `heap[0]` for storage.
