 * large to accomodate typical inputs. It does not have to be a dynamically
 * allocated type with potentially unlimited width: consider the width of
 * an integer defined here as one of the "compiler limitations".
 * NOTE: this is NOT a type for ASN.1 "INTEGER" type representation, this
 * type is used by the compiler itself to handle large integer values
 * specified inside ASN.1 grammar.
