Can you declare multiple variables at once in Go?

In terms of language specification, this is because the variables are defined with:

VarDecl     = "var" ( VarSpec | "(" { VarSpec ";" } ")" ) .
VarSpec     = IdentifierList ( Type [ "=" ExpressionList ] | "=" ExpressionList ) .

(From "Variable declaration")

A list of identifiers for one type, assigned to one expression or ExpressionList.

const a, b, c = 3, 4, "foo"  // a = 3, b = 4, c = "foo", untyped integer and string constants
const u, v float32 = 0, 3    // u = 0.0, v = 3.0

Yes, you can:

var a, b, c string
a = "foo"
fmt.Println(a)

You can do something sort of similar for inline assignment, but not quite as convenient:

a, b, c := 80, 80, 80
