Example 1:
class MyClass { }
var myC = new MyClass()?;
proc libFun(myArg) {
var myClass = myArg: class; // error here
}
proc main {
libFun(myC);
}
currently reports
error: const actual is passed to a 'ref' formal of chpl__initCopy()
whereas it should say ex. “cannot transfer ownership from a const variable”
Example 2
class MyClass { }
const c1 = new MyClass();
proc myFun(myArg) {
var c2 = new MyClass();
c2 = myArg; // error here
}
proc main {
myFun(c1);
var c3 = new MyClass();
c3 = c1; // error here
}
currently reports
error: cannot assign to const variable
whereas it should similarly say ex. “cannot transfer ownership from a const variable”
