'open' probes the outside world, and programs should be prepared for such probes 
to fail. In contrast, 'cons' is basic memory allocation, just as calling a 
function is basic memory allocation. We don't require programs to check each 
function call to see whether the call failed because the stack was exhausted. 
Similarly we don't require programs to check each call to 'cons' to see whether 
'cons' failed because the heap was exhausted.
