can someone explain why a++ works in a string template but not a+=1

[tseisel]

a++ is an expression whose result is a, then a is assigned a + 1.
a +=1 is a statement. Just like an assignement, it does not return an expression and therefore is not assignable.
Only expressions are allowed in string templates.
