Support for IndexExpression

Is your feature request related to a problem? Please describe.

I have an expression that uses a dictionary. But I can’t serialize it as Serialize.Linq do not support IndexExpression.

Describe the solution you’d like

Suport for IndexExpression so that something like:

Expression<Func<Dictionary<string,string>, bool>> filterExpression = filter => (int)Convert.ChangeType(filter["Age"], typeof(int)) < 10;

can be serialized.

Background

I’m building a messaging system where developers may filter messages using LINQ expressions.

A dev might use something like: subscription.Filter<MyDTO>(x => x.Age < 10).

But since the messaging system doesn’t have access to the assembly that the MyDTO type is located in I’m transforming the expression to use a Dictionary<string,string> instead before transferring the expression to the messaging system.

That’s why I have wierd looking expressions 😃
