There are two major issues with Go error handling:
1. It is not strict enough, i.e. the compiler cannot ensure error check
2. It is not consistent enough.
In the first you can easily ignore an error and the compiler will let you
go further. In the second, you can both
*if err := doSomething(); err != nil {*
*}*
and
*v, err := returnSomething()*
*if err != nil {*
*}*
*or err* would do this better for sure
*doSomething() or err {*
*}*
and
*v := returnSomething() or err {*
*}*
