Go doesn't have exceptions, so scope(failure/success) makes no sense.
You can argue about if not having exceptions is good or bad (I don't
have a strong opinion about it, sometimes I feel exceptions are nice,
sometimes I think they are evil), though.
Just to compare the two styles...
Without exceptions, every step of the code must be checked explicitly:
// C code:
int foo()
{
int err = 0;
// allocate resources
err = bar();
if (err) goto finally;
err = zar();
if (err) goto finally;
err = car();
if (err) goto finally;
finally:
// do cleanup
return err;
}
(Ordinarily, the if(err) checks are hidden inside macros like
check_error, check_error_null, etc.)
With exceptions, the actual code emerges:
// C++ or D code
void foo()
{
// allocate resources
bar();
zar();
car();
}
