#nowarn "49" // no warning for uppercase variable names
// ----------------------------------------------------------------------------
// Mutable Tuples - used when translating queries that use F# tuples
// and records. We replace tuples/records with anonymous types which
// are handled correctly by LINQ to SQL/Entities and other providers.
//
// NOTE NOTE NOTE NOTE NOTE NOTE NOTE NOTE NOTE NOTE NOTE NOTE NOTE
//
// The terminology "mutable tuple" is now incorrect in this code -
// "immutable anonymous tuple-like types" are used instead. The key thing in this
// code is that the anonymous types used conform to the shape and style
// expected by LINQ providers, and we pass the correspondence between constructor
// arguments and properties to the magic "members" argument of the Expression.New
// constructor in Linq.fs.
//
// This terminology mistake also runs all the way through Query.fs.
