   STC supports mutability of `GString` too, so it would be a breaking change anyway. If some user changes the strings/values via the bad practice and is impacted by the change, creating a new `GString` instance could be a workaround.
   
   ```
   @groovy.transform.CompileStatic
   def x() {
       def s = "a${1}b"
       s.strings[0] = 'c'
       s.values[0] = 2
       s
   }
   
   x()  // yields c2b
   ```
