orelse must return an error (ie satisfies the error interface); the
specific type and variable name do not matter.
But how does "orelse" perform the check in the first place? Does it look
for the variable named in the return statement?
var foo error
r, bar := os.Open(src) orelse return foo // does this do "if foo != nil {
return bar }" ??
Also, you are explicitly allowing bare return. In that case, does it look
at the return values in the function definition? If the function returns
multiple values, how does it know which one?
