There is definitely an overhead issue, but the bigger question is why you 
think this would be a good idea.

The big advantage of using a Perl API is its expressiveness and 
flexibility. Perl is a programming language. HTTP + JSON|XML|YAML is not a 
programming language, and as such is much less flexible.

What possible benefit could you get from using REST the way you propose, 
that's not outweighed by the massive downsides?
