I know this was just a rough example, but I just wanted to point 
this out:  It is not a good idea to use enforceEx() here, since 
a) it uses new to allocate memory for the exception, and b) you 
shouldn't try to allocate at all when you're out of memory.  :)

Use core.exception.onOutOfMemory() to signal an allocation 
failure instead.  It throws a pre-allocated OutOfMemoryError.
