What does it mean that a programming language is a formal programming language? And which languages are formal programming languages? And which are informal programming languages?

Are there any objective measures for measuring the power of programming languages? Turing-completeness is one, but it is not particularly discriminating. I also remember there being a few others measures of power which are more limited versions (like finite-state-autonoma), but is there any objective… >>> More
