~~That does work because of the super-low-precedence of 'or'.~~Actually, it doesn't work. The `if` wants to evaluate all of the following expression. It's not very readable, ~~though~~either.~~: someone who doesn't understand the lower-precedence-ness of 'or' (compared to '\|\|', especially). To them it would look like you should~~It will try to eval $PAGE if one of the two or statements is true. Also, you don't need to specify main-> for nopageerror. For clarity, I suggest one of these: `# whoops, syntax errors, thanks to Roy Johnson ## ( eval "$PAGE" if main->can($PAGE) ) or nopageerror; ## or... #( eval "$PAGE" if main->can($PAGE) ) # or nopageerror; ## or... if ( main->can($PAGE) ) { eval $PAGE } else { nopageerror }` [download] Updates: 2005-09.Sep-30 : fixed stupid errors as pointed out by Roy Johnson. Don't code without coffee, kids! :-) <-radiant.matrix-> Larry Wall is Yoda: there is no `try{}` (ok, except in Perl6; way to ruin a joke, Larry! ;P) The Code that can be seen is not the true Code "In any sufficiently large group of people, most are idiots" - Kaa's Law	[reply] [d/l]

predicate-`if` is not an operator, it is a statement modifier. It is not part of an expression, so you can't parenthesize it. Your first suggestion is a syntax error. Caution: Contents may have been coded under pressure.	[reply] [d/l]

You are correct radiant.matrix. I'm always forgetting the \|\|/or methods. Simularily I confuse the eq and = and == thus causing scripting errors.... The simplest things are generally the easiest to over look and cause the most problems.	[reply]
