PLP was made because I didn't like the syntax of the existing
web Perl embedders.
From
http://plp.juerd.nl/:
There is no need to learn a complete language and you won't have to know an object model.
That means any perl coder can go right ahead, even if he or she refuses to read documentation. In the upcoming version, this is even more so.
