But it wouldn't be Perl if it wasn't possible to implement a perlish equivalent to JavaScript's bind() in a completely transparent and idiomatic fashion with just a few lines of code.

You will encounter double encoded UTF-8 or arbitrarily thrown in question marks in a seemingly random fashion. How can this be avoided?

None of them offered all of the features that I considered a must for the V in the imperia MVC framework. Some of the more important design decisions behind it are outlined below, giving you some insight into the anatomy of a modern template processor.

But it is still part of the boilerplate code of many Perl module authors who are not aware to which extent they are harrassing their users and their users' users by forcing them to become involuntary beta testers.
