Nah, dynamic languages suck even more.  Particularly interpreted ones.

   let ids =
     try List.map int_of_string (String.nsplit cpulist ",")
     with Failure "int_of_string" ->
       raise (VirshError (cpulist ": invalid format"))

That's the same code (actually better - not only does it do the check, 
but it converts the CPU numbers to a list of integers for you), safer, 
the same speed as the C code, and a factor of 10 shorter.

Rich.
