Indeed, the way you wrote it, it would work. In my original design, the variable would be in a different package, so neither 

use vars qw(%MyApp::once);

[download]
nor 
our %MyApp::once;

[download]
would have worked, because package qualifications are not allowed in use vars and our; put actually I don't need to put once in its own package; I can simply have it in my current package, and this would make your solution indeed feasible.
