A long overdue change is now committed dicussed around more then a year ago.
The short story:
* interpreter-code is now a PackFile_ByteCode pointer
* the shortcut pointers to prederef or jit_info are gone
* switching a bytecode segment for a function call or return is now
basically just one C

Would you want this:
sub infix:myeq(Str $a, Str $b) { return ($a eq $b) ? $a : ''; }
to be:
sub infix:myeq(Str $a, Str $b) { return ($a eq $b) ? $a but bool::true:
