Is this safe?
class A {}
immutable(A) getA()
{
A a;
// .. do stuff with a
// not leaking a to any functions
// is this safe????
return cast(immutable A)a;
}
What if A is replaced with A[] or A[int]?
If it's not safe, what would be the proper way to return an
immutable instance from a function which needs to make
adjustments to the instance before returning it as immutable?
