Re: Testing package membership

You can ask with $ref->can('methodname') or yourpackage->can('methodname') if such a method exists (which will not work if AUTOLOAD is in effect, but otherwise it's fine).

can is defined and documented in UNIVERSAL.

Got it! Using `->can()` wrapped in `eval{}` does the trick nicely: `package Util::Stuff::abc; sub attrib1 { 1 } sub attrib2 { 10 } ... eval { if ($symref->can('attrib1')) { ... $symref->attrib1 is OK ... }};` [download] Thanks to GrandFather and moritz.	[reply] [d/l] [select]

Hmm, looks like AUTOLOAD is in effect since ->can() is failing. Looks like I'm stuck with eval{}, unless there's another way.	[reply]

can can fail for reasons other than AUTOLOAD. Class::AutoloadCAN	[reply]
