Hello. The following code compiles OK where func creates a
mutable array and main assigns it to an immutable variable:
int[] func(int x) pure {
int[] result = new int[10];
result[0] = x;
return result;
}
void main(string[] args)
{
immutable int[] array = func(1);
}
I assume this works because func is pure so that the compiler
knows that its return value won't be changed by some other code.
But it doesn't compile when I put the same code from func
"inline" into main:
void main(string[] args)
{
int[] result = new int[10];
result[0] = 1;
immutable int[] array = result;
}
I could forcibly cast result to immutable int[], but that seems
error-prone. How to tell the compiler that result will not be
changed after assigning to array so that the immutable assignment
compiles?
