Address of a temporary in Go?

Question

What\'s the cleanest way to handle a case such as this:

func a() string {
    /* doesn\'t matter */
}

b *string = &a()

This generates the

Answer 1

In the end you are proposing that Go should allow you to take the address of any expression, for example:

i,j := 1,2
var p *int = &(i+j)
println(*p)

The current Go compiler prints the error: cannot take the address of i + j

In my opinion, allowing the programmer to take the address of any expression:

• Doesn't seem to be very useful (that is: it seems to have very small probability of occurrence in actual Go programs).
• It would complicate the compiler and the language spec.

It seems counterproductive to complicate the compiler and the spec for little gain.
