if ($] < 5.600) {
warn "our isn't implemented";
}
Note that 'use vars' is supposedly depreciated, so don't
use it if your script depends on 5.6 features. Placing
'our' in a lexical scope probably makes it externally
visible until you leave the scope, 'use vars' imports
into your symbol table. Hope this is right :)
