Certainly. Sorry that I missed "but" before "as long as", which made
me sound as if I were unhappy. At least, I didn't call it an ugly
The alternative you mentioned up-thread "... to write out "return
error(...)" as "error(...); return -1". In some ways that is more
readable, though it is more verbose..." has one more downside you
did not mention, and the approach to encapsulate it inside error()
will not have it: new call-sites to error() do not have to worry
about the issue with this approach.
Until it breaks, that is. But that goes without saying with the
"it's something we can count on" pre-condition in place ;-).
