Do we have a preg_callback equivalent in Perl ?
Lets say I want to match something and replace it with the return value of the function that is called with the matched thing.
I'm wondering if there is an equivalent to Qt's signal/slot mechanism for Perl. I have looked into POE, but since it's huge, I couldn't find anything useful.
Thank you in advance,

If I have a hash in Perl that contains complete and sequential integer mappings (ie, all keys from from 0 to n are mapped to something), is there a means of converting this to an Array?
I know I could iterate over the key/value pairs and place them into a new array, but something tells me there should be a built-in means of doing this.

how convert string into Unicode string in Perl.
I am looking some attribute in LDAP which accepts only Unicode string .
So i want to convert normal string to Unicode string
i can thought that it will open a shell, execute the parameter (shell command) and return the result in a scalar.
But, execute 'system' function in a perl script is faster than a shell command.
It will call this command in C?
If yes, what's the difference between
rmdir foo
and
system('rmdir foo');
Thanks,

Is it possible to use a Perl hash in a manner that has O(log(n)) lookup and insertion?
By default, I assume the lookup is O(n) since it's represented by an unsorted list.
I know I could create a data structure to satisfy this (ie, a tree, etc) however, it would be nicer if it was built in and could be used as a normal hash (ie, with %)
