I think try-catch simplifies writing error handling code, but not
necessarily simplifies understanding or modifying it once it is
written.
I, too, like the if err!=nil {} as it is. One improvement I can think
of is reducing the boilerplate by implementing a macro-like
extension:
func f() {
handle openErr(err) error {
return err
}
x, openErr:=os.Open(...)
openErr would be called if the error is non-nil. Some months ago I did
write a proposal similar to this, and I was not the only one thinking
along the same lines. It is backward compatible, and the code is still
readable in my opinion.
