sub Oxff cannot start with a number...(without symbolic refs tricks like

% stephan@armen (/home/stephan) %
% perl -we ' *{"11abc"} = sub { print q[ok] }; *{"11abc"}{CODE}->()'
ok

% stephan@armen (/home/stephan) %
% perl -we ' *{"11abc"} = sub { print q[ok] }; &{*{"11abc"}}()'
ok

actually I think the second form could work with less braces ...humm
