type GeneratorOptions …

// MergeGlobalOptionsIntoLocal merges two instances of GeneratorOptions.
// Values in the first 'local' argument cannot be overridden by the second
// 'global' argument, except in the case of booleans.
//
// With booleans, there's no way to distinguish an 'intentional'
// false from 'default' false.  So the rule is, if the global value
// of the value of a boolean is true, i.e. disable, it trumps the
// local value.  If the global value is false, then the local value is
// respected.  Bottom line: a local false cannot override a global true.
//
// boolean fields are always a bad idea; should always use enums instead.
