I *fully* support this idea. A suggestion though:
return hash (references) *as well as* lists.
I've proposed that the want() function will be able to distinguish
a HASHREF context (there the return value is used as a hash reference).
Retain the list return (which is convenient why one does know what
(caller(0))[4] does), and have the named return values returned via
a hash reference when such a context is active.
E.g.:
$package = caller; # scalar context
($package, $file, $line, $subname) = caller(0); # list context
$subname = caller(0)->{subname}; # hashref context
