Hmm.  Global (and static) initializers that are defined inside functions 
are placed in an anonymous lambda which is evaluated when the appropriate 
function declaration is evaluated.  Global initializers not inside a 
function are simply evaluated in place.  That's clearly broken, but 
somewhat difficult to fix as there isn't a 'hook' to hang the initializer 
code onto.  I'll have to rework the compiler a bit to provide a place for 
this initializer code to sit in this case.  Fortunately the virtual machine
won't have to change at all.

Somehow static is no longer a synonym for global at top level.  Is there 
any reason for it not to be?
