In fact, this is actually exactly equivalent to you sample. Global and class
variable initialization on Swift is performed lazily and is implemented using
dispatch_once().
And after a second thought, I think that it should be 'let' and not 'var', and
you don't want the pointer to be changed after initialization.
I don't remember if static class variable are supported yet, but if they are,
you can also use one instead of a global.
