Proposal

I think Go can add some syntax sugar that make the error handling easier. Developer can mark an error with a marker/operator and if this marked error is not 'nil' it's value will be returned.

Example

'''go
err! := example.ShouldRetErr()
'''

The '!' operator will simulates checking the err value and returning it if it's not 'nil' (maybe replace it with if statement behind-the-scenes) and we don't need to rewrite the if statement every time we get an error as a return.

The if statement errors handling still doable which guarantees backward compatibility.
