Podmaster has kindly informed me that this code works fine on 5.7 and 5.8.

He also pointed out that I should mention that on Win32 if you have nmake.exe that you will need to patch the makefile.pl that comes with Scalar::Util so that it uses nmake instead of make. (Almost the last line in the script.) Othwerwise it will fail a pretest and claim incorrectly that the code can't be built on your system.
