 ### Globals
 
 Global variables are also defined using a special operation,

 Since functions need to be isolated-from-above, i.e. values defined outside the

 locally define a value containing the _address_ of a global. The actual value
 can then be loaded from that pointer, or a new value can be stored into it if
 the global is not declared constant. This is similar to LLVM IR where globals
