Smart Pointers

Sric provides C++-style smart pointers including SharedPtr, and WeakPtr.

SharedPtr

Reference-counted with some overhead. Can be created from existing own*:

var p = new Int
var sp: SharedPtr$<Int> = toShared(p)

Convertible with own*:

var p = sharedPtr.getOwn()
sharedPtr.set(p)

WeakPtr

Breaks circular references that could cause memory leaks with own*/SharedPtr:

var p = new Int
var wp: WeakPtr$<Int> = toWeak(p)

Use via lock() which returns nullable own*:

var sp : own*? Int = wp.lock()

Returns null if referenced object was freed.
