Re: Exists and autovivification (was: Looping through a hash reference...)

Code such as

  $bazref = \$foo{bar}{baz}
[download]

too relies on autovivification.

Good point. Taking a reference of anything would have to autovivify it. We're not really tightening our belts, it just feels that way because we're getting fatter.	[reply]

Taking a reference is an "lvalue context". So this isn't an exception but part of the same rule. Even in C, you can't take the address of a non-lvalue (it might be 'const' aka 'read-only', of course). The `$hash{key1}{key2}` autovification of 'key1' has long been considered a minor bug. So I'd hope that backward compatability to bugs isn't a good reason to a prevent fixing them. - tye	[reply] [d/l]
