Declaring a variable without assigning

Question

Any way to declare a new variable in F# without assigning a value to it?

Accepted Answer

See Aidan's comment.

If you insist, you can do this:

```
let mutable x = Unchecked.defaultof<int>
```

This will assign the absolute zero value (`0` for numeric types, `null` for reference types, struct-zero for value types).
