Golang if/else not compiling, function ends without a return statement.

Question

I cannot figure out why this will not compile. It says functions ends without a return statement, but when I add a return after the else, it still won't compile. func (d Foo) primaryOptions() []string{ if(d.Line == 1){ return []string{"me", "my"} } else{ return []string{"mee", "myy"} } }

Go forces else to be on the same line as the if brace.. because of its "auto-semicolon-insertion" rules. So it must be this: if(d.Line == 1) { return []string{"me", "my"} } else { // <---------------------- this must be up here return []string{"mee", "myy"} } Otherwise, the compiler inserts a semicolon for you: if(d.Line == 1) { return []string{"me", "my"} }; // <---------------------------the compiler does this automatically if you put it below else { return []string{"mee", "myy"} } ..hence your error. I will link to the relevant documentation shortly. EDIT: Effective Go has information regarding this.
