To echo btrott, that's a symbolic reference which is quite confusing and easy to write incorrectly.

As I read it, there's an object name stored in $_. It's interpolated into pseudo-existence ($) and rereferenced (\), which lets you call its insert() method. Very ugly.

A better way to create variables at run time is by making them anonymous and storing them in some sort of data structure -- an array or a hash, for example. Novice programmers often tie themself up in loops trying to create uniquely named variables and store the names just to get at them later. Instead, learn how to use arrays and hashes and objects as containers, and save the sweating for the tricky stuff.
