Re: Interrogating stashes - Camel example doesn't work?

The "*foo{THING}" notation is used to get a reference to a slot of a typeglob or undef if that slot is unused (except that it creates a scalar if one doesn't exist).

You want:

... if *sym{ARRAY};
... if *sym{HASH};

or *{ $main::Env::{$symname} }{ARRAY} or even just *{ $Env::{$symname} }{ARRAY}.

I remembered having applied myself to study of this "*foo{THING}" technique in the dim past. Thanks! - Soren Jul 28, 2025 at 00:54 UTC	[reply]
