note adrianh <p>Read [id://26319] and [id://72247] and repeat to yourself three times - "('foo', 'bar', 'baz') is not an array" ;-)</p> <p>I'm with [Abigail-II]. The \ operator has lots of weird cases that surprise you. For example: <code> \@foo # reference to array @foo \(@foo, $a) # list of reference to array @foo and scalar $a \(@foo) # list of references to contents of @foo </code> 285498 286098
