A related question is whether to group multiple catch clauses together or
break them up, i.e. turn

try { ... }
catch (int) { ... }
catch (...) { ... }

into

try 
 {
  try { ... }
  catch (int) { ... }
 }
catch (...) { ... }

The grouping does seem like a syntactic convenience more than anything
else, but I'm not sure that breaking them up buys us anything either.
