Why is in Go design ++
and -
++
and --
are statements, not expressions?
Probably to be explicit. Assignment is not an expression in Go and results in a syntax error.

Go has no comma operator and ++ and – are statements not expressions. Thus if you want to run multiple variables in a for you should use parallel assignment (although that precludes ++ and --).
for i, j := 0, len(a)-1; i < j; i, j = i+1, j-1 {
a[i], a[j] = a[j], a[i]
}
