If the reference is a simple scalar, you can just say `@$href{@keys}`. The curly braces around the reference are only necessary if the reference is a more complicated expression (e.g. `@{gimme_href()}{@keys}`). Same thing goes with using a slice or `$#` (last index) on an array reference: `@$aref[@indices]` and `$#$aref` or `@{gimme_aref()}[@indices]` and `$#{gimme_aref()}`. Of course, if the curlies make it more clear to you, by all means use them.	[reply] [d/l] [select]

@$href{@keys}

@{gimme_href()}{@keys}

Same thing goes with using a slice or $# (last index) on an array reference: @$aref[@indices] and $#$aref or @{gimme_aref()}[@indices] and $#{gimme_aref()}.

Of course, if the curlies make it more clear to you, by all means use them.
