I don't think this is true. I haven't found a use of goto that can't be
converted into a simple wrapper function with return statements, e.g.,
do_something_impl(...){
//Do something...
if(failure)return error;
//Do something else...
if(failure)return error;
//...
return success;
}
do_something(...){
//Allocate resources
//...
ret=do_something_impl(...);
//Free resources
//...
return ret;
}
You can argue about whether or not that's any cleaner than using goto,
and I wouldn't insist that you don't, but at least this makes it clear
that you can't get out of do_something() without cleaning up your
resources (in this particular example), yet doesn't require code
duplication or macros.
