in reply to Looking for testers who use Microsoft compilers

I tried running your example code in my version of blead perl (5.31.6) on Linux, compiled with mostly default settings, using List::Util 1.53. It fails tests 1, 4, and 5.
map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]

    Yes - if you upgraded to version 1.54 on that particular build of perl it would pass all 5 tests.
    On Linux, it's only when $Config{nvsize} exceeds 8 that you'll generally get either test 2 or test 3 (depending upon $Config{nvtype}) to fail with 1.54.
    (Note that this particular script doesn't correctly test IBM doubledoubles because I figured it's not going to encounter any of those rare types here.)

    Thanks, choroba.

    Cheers,

      Confirmed. After the upgrade, all tests pass.

      map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]
