    Isn't there an error in this ?!

    It neighter seems to suppress the warning, nor do I understand how this is supposed to work. :(

    Thanks,

      Why didn't you show what you tried instead of just saying what amounts to "Does not!" 

      >perl -wle"$MyApp::once{x} ||= 1;"
Name "MyApp::once" used only once: possible typo at -e line 1.

>perl -wle"%MyApp::once if 0; $MyApp::once{x} ||= 1;"
