Re: object ref syntax

If i do my $b=$bar."_edit" and $o->$b() it works, but I don't wanna make temp vars like that.

But that's about the only way to do an indirect method call. You can horse around with UNIVERSAL::can to get at it a bit differently, but you're still gonna end up with either a temporary variable or a value in passing.

Symbolic method calls are rare enough that it was deemed reasonable to restrict them to simple scalars.

Just to elucidate on merlyn's `can` method (no pun intended), the following works just fine: `$b = "foo"; $o->can($b . "_edit")->();` [download] bbfu Seasons don't fear The Reaper. Nor do the wind, the sun, and the rain. We can be like they are.	[reply] [d/l] [select]

If you call a method like a function, and in this case you do, you want to pass the object as the first argument. `$o->can($b . "_edit")->($o);` -Anomo	[reply] [d/l]
