what does LINQ offer that UFCS-style functional programming
does not?
LINQ basically is a UFCS-style api. AST reflection is what makes
it nice.
consider:
X.Where(x => x.Members.Count() == x.Admins.Count())
straightforward in both D and C# when X is an array or container
type.
When X is a table in a database, things get tricky for D.
C# can interpret the lambda as an Expression<Func> (an AST type),
so the implementation of X can reflect over the body of the
lambda and use it to generate the appropriate SQL. ORMs such as
entity framework and nhibernate do this now.
