I have one (very) general comment. Since we are talking about the 
halting problem, completeness etc. Since time is in essence the 
problem, would it be possible to annotate a function with a 
timeout (physical or virtual time) which leads to the bottom type 
if exceeded? This could in theory be very useful.
