Overview

A declared variable's binding and its declared Rubycc::Type. When global is false it is a local: storage is a virtual-register number for a scalar (int or pointer) and a stack object id for an array, which one following from type.array?. When global is true it is a file-scope variable and storage is its symbol name (a String), whose address :global_addr materializes. const records whether the object is top-level const-qualified, so a write to it (a plain assignment, a compound assignment or "++"/"--") is diagnosed as writing a read-only variable; reads and "&" are unaffected.
