///////////////////////////////////////////////////////////////////////////////
// This file is home to helpers that convert from various base types to
// respective pointer types. This is necessary because Go does not permit
// references to constants, nor can a pointer type to base type be allocated
// and initialized in a single expression.
//
// E.g., this is not allowed:
//
//    var ip *int = &5
//
// But this *is* allowed:
//
//    func IntPtr(i int) *int { return &i }
//    var ip *int = IntPtr(5)
//
// Since pointers to base types are commonplace as [optional] fields in
// exported thrift structs, we factor such helpers here.
