Using one of the many suggestions for the syntax, please change to what
you end up with:
int t = boost::convert
<int>
::from("17", []{
   log("could not read noOfThreads");
   throw ConfigError(); });
int c = boost::convert
<int>
::from("17", []{
   log("could not read noOfCores, using default");
   return 7; });
That looks cool. We might provide a bunch of callables to cover

Right :-)
How about
non-throwing failure detection? What should be the signature for that
behavioral callable? optional<T> op()()?
Personally, I would not use that (preferring either default or
exception), but yes, I guess so.
