+<p>This type is only useful as a pointer target. Do not use it as a
+return type for FFI functions which have the <code>void</code> return type in
+C. Use the unit type <code>()</code> or omit the return type instead.</p>
+
+<p>For LLVM to recognize the void pointer type and by extension
+functions like malloc(), we need to have it represented as i8* in
+LLVM bitcode. The enum used here ensures this and prevents misuse
+of the &quot;raw&quot; type by only having private variants.. We need two
+variants, because the compiler complains about the repr attribute
+otherwise.</p>
