I think you are assuming bottomless grit and determination on the part of the hapless punter. He is prepared to invest endless effort in learning whatever language is thrown at him, whatever the syntactic idiosyncrasy, and however incomplete the documentation. The reality is that I [ is it only me ? ] rapidly lose the will to live when diverted from my main goal of problem solving by syntax issues. I guess what we need is a Babel Fish for Mathematics software. Where is Douglas Adams when you need him ?
