+// This class calculates the slots that values will land in. This is useful for
+// when writing bytecode or assembly out, because you have to know these things.
+//
+// Specifically, this class calculates the "type plane numbering" that you see
+// for a function if you strip out all of the symbols in it. For assembly
+// writing, this is used when a symbol does not have a name. For bytecode
+// writing, this is always used, and the symbol table is added on later.
