Optimizing Aggregate for String Concatenation [closed]

Answer 1

You are 'overriding' System.Linq.Aggregate with your own extension method in namespace MakeAggregateGoFaster.

Perhaps specialised on IEnumerable and making use of a StringBuilder?

Maybe taking an Expression> instead of a Func so it can analyse the expression tree and compile some code that uses StringBuilder instead of calling the function directly?

Just guessing.
