Remove function?

[seany]

Hello, I want to remove a car form a string.

hence i used the remove function from std.algorithm, and i had 
this :

string stripPar(string S)
{
        while(S[0] == '(' && S[S.length-1] == ')')
        {
        
             S = S.remove(0);
             S = S.remove(S.length-1);
        }

        return S;
}

(taking help from this: 
http://www.digitalmars.com/d/archives/digitalmars/D/learn/std.algorithm.remove_strange_behavior_removing_items_for_the_dynamic_35713.html)
I was having this error:

So I changed them to
string stripPar(string S)
{
        while(S[0] == '(' && S[S.length-1] == ')')
        {
        
              S.remove(0);
              S.remove(S.length-1);
        }

        return S;
}
(i.e. not S = S.remove any more)

But I am having the smae error again ..
