What did you do?
I created a function that (unintentionally) did what the following basic example does: func DoSomething() (val int) { return val }
What did you expect to see?
A compile error about not returning a value.
What did you see instead?
It compiled and ran fine. Because of variable masking, I was setting a locally scoped variable instead of the return value, which caused it to always return 0.
The text was updated successfully, but these errors were encountered:
That is how the language works. Named result parameters are in scope within the function body. You can assign to them. You can use return with no values to return the values that are currently in the named result parameters (https://golang.org/ref/spec#Return_statements). You can change the values of the result parameters in deferred functions (https://golang.org/ref/spec#Defer_statements).
