Is there a case that ->can is needed that is not caught by UNIVERSAL::callback ? No, afaik; it rather catches too much. If some package ought to have a callback method which it hasn't due to some fubar, UNIVERSAL::callback kicks in - long faces, head-scratching. But! if someone writes a method/function for package UNIVERSAL, they should know what they are doing, and my bets are that you do.
perl -le'print map{pack c,($-++?1:13)+ord}split//,ESEL'
