Unsafe Pointers

Fyr supports unsafe pointers, which are comparable to C-pointers. They have pointer arithemtics and can be casted freely. Consequently, unsafe pointers are as dangerous as C-pointers since the compiler does not provide any checks. Idiomatic Fyr code does not use unsafe pointers at all. Unsafe pointers are used for low-level programming or when interfacing with C code.

let ptr #int32 = 0x20
*ptr = 1
*ptr = 2
