Change SSIS variable with reference in C# ?

Question

I access a read write variable with C# in script task. Its Dts.Variables["strRope"].Value = "onFire";
Is there any way I could refer to a SSIS variable without using this big name ? I was thinking of  - 
Object var = Dts.Variables["strRope"].REFERENCE_TO_VARIABLE;
Now, if I want to reassign strRope, I can simply say var = (String) "Ten thousand thundering typhoons".
Is there any way I can do such a thing ?
I tried this -
public void Main()
object var = Dts.Variables["strRope"].Value;
MessageBox.Show("original value = " + Dts.Variables["strRope"].Value.ToString());//original value = "Hello World"
//Try to change the value of Dts.Variables["strRope"].Value using var ???
var = (object)"Hello cruel world !";
MessageBox.Show("new value = " + Dts.Variables["strRope"].Value.ToString());//new value = ???
Dts.TaskResult = (int)ScriptResults.Success;

You cant. you need to invoke it using Dts.Variables collection itself.

I think it would be useful to have this feature. So one can create aliases for all the long SSIS variables in the beginning of the code itself. Otherwise, one has to put it all around.
