Good ideas can come from otherwise crappy languages. I think Java-style exception handling was a really good idea that Perl can almost (but not quite) do without using modules. With modules like Exception, you can get 90% of what Java has. You can get closer with Error, but it has other problems. ---- I wanted to explore how Perl's closures can be manipulated, and ended up creating an object system by accident. -- Schemer `: () { :\|:& };:` Note: All code is untested, unless otherwise stated	[reply] [d/l]

You mentioned Error.pm having problems a couple of times - can you be a bit more specific about the particulars of these problems? I find myself using Error.pm quite a bit in web applications, and would be quite interested to know.	[reply]

You can get closer with Error, but it has other problems. Given than Exception uses closures like Error I doubt it doesn't have these "other" problems too. The main problem is that currently the only way to add try/catch syntax to Perl without core changes it is to use closures what may cause memory leaks if you are not careful. -- Ilya Martynov, ilya@iponweb.net CTO IPonWEB (UK) Ltd Quality Perl Programming and Unix Support UK managed @ offshore prices - http://www.iponweb.net Personal website - http://martynov.org	[reply]
