This is just a slightly more complex version of the "convert a list to a hierachical hash subscript" question.
use strict;
use warnings;
use Data::Dumper;
my $data = str2data('foo[1].bar.baz[0]', 123);
print Dumper($data), "\n";
sub str2data {
my($string, $value) = @_;
my $r = \my $return;
$r = $1 ? \$$r->{$1} : \$$r->[$2]
while $string =~ /\G(?:\.?(\w+)|\[(\d+)\])/g;
$$r = $value;
$return;
}
Note - I'm assuming that the input is known to be valid and that $1 can never be '0'. If $1 could ever be '0' then insert 'defined' in the obvious place.
