I agree with your statement that tapset authors would like familiar "C" 
syntax but end users who write the scripts would like a simpler script 
kind of language. I think this difference is understandable due to 
different needs.
I am not sure i understand what you mean by  " we might sacrifice the 
convenience of C for something with better safety properties ". Are you 
suggesting a different language for end users if so what would that be 
and how it is going to achieve safety properties.
