Sigil reference

A quick reference of the sigils and their meaning:

Sigil	Meaning
~	Owned pointer; like a normal value, but always pointer-sized, and allocated on the heap
&	Borrowed pointer; a pointer to data that you do not own and thus cannot free
&mut	Mutable borrowed pointer; like a borrowed pointer, but cannot alias with any other pointer, and you can mutate through it
@	Managed pointer; a pointer to data that no one owns. Allows cycles. Garbage collected
'	Lifetime/label marker; used to label loops for labeled break and to indicate the lifetime of a borrowed pointer (eg &'a T)
*	Raw pointer; just like a pointer in C. Requires unsafe code to dereference. Can be NULL
