The code you've shown does only handle methods. ->can does also handle normal subs. Cheers Rolf _{(addicted to the Perl Programming Language and ☆☆☆☆ :) Wikisyntax for the Monastery}	[reply]

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'	[reply] [d/l] [select]

Checking ->can is cleaner than adding a fallback method to UNIVERSAL. Cheers Rolf _{(addicted to the Perl Programming Language and ☆☆☆☆ :) Wikisyntax for the Monastery}	[reply]
