Hi dlang community,
I'm trying to implement a "reset" functionality which should 
revert all variables to the program start initial state.

Example:

import Graph;
protected Edge[string] m_string2edge;

int main()
{
    // adding some elements
    // not important how it works
    // m_string2edge[name] = e;

    // resetting it
    m_string2edge = null;
    m_string2edge = new Edge[string]; // <- won't compile

    return 0;
}

How do I revert my variable to the init state?

Thanks in advance,
Simon

You can use m_string2edge.clear() if you want to remove all 
entries from m_string2edge.
