Tips and Traps¶

1. Golang implements the type Tuple in the standard library go/types, however, Tuple is NOT a first class citizen in Golang.

2. Multiple return parameters in Golang is implemented via Tuple in a limited way (since Tuple is not a first-class citizen).

   • Tuple can only be used as multiple return parameters/values currently.

   • Since Tuple is not a first-class citizen, you cannot use a Tuple to receive multiple return values. Instead, you have to use define multiple variables to receive multiple return values.

   • Nested types is NOT allowed as return parameters.
