Missing return on block expression

[steverzag]

The fallowing is the expression view using Readable Expressions from a code block expression.

var result = 1;
while (true)
{
    if (value > 1)
    {
        result= result * value;
        value--;
    }
    else
    {
        break;
    }
}

This is the same block used in the loop expression chapter from Microsoft Expression Tree learning

// Creating a parameter expression.
ParameterExpression value = Expression.Parameter(typeof(int), "value");

// Creating an expression to hold a local variable.
ParameterExpression result = Expression.Parameter(typeof(int), "result");

// Creating a label to jump to from a loop.
LabelTarget label = Expression.Label(typeof(int));

// Creating a method body.
BlockExpression block = Expression.Block(
    new[] { result },
    Expression.Assign(result, Expression.Constant(1)),
        Expression.Loop(
           Expression.IfThenElse(
               Expression.GreaterThan(value, Expression.Constant(1)),
               Expression.MultiplyAssign(result,
                   Expression.PostDecrementAssign(value)),
               Expression.Break(label, result)
           ),
       label
    )
);

Basically the interpreted code lacks the return statement, which should be like => return result;
