We were emitting this at global scope (not in Globals). That would lead to errors about the variable needing to be in the constant address space. (You can see the result in ConstArray.metal - the old code was invalid). Also, we were already making references use _globals, so the code was double-wrong (or half-right, depending on your perspective). After the core change, writeVarDeclaration was only used for local scope, and writeModifiers never used the 'globalContext' parameter. The removal of finishLine() changed every test output, unfortunately.
