One problem with 'length' is that is not a keyword in all contexts, and so
an innocent coding mistake such as the one below can occur and is
manifested at run time. And even then its not so easy to see if you're not
focusing on 'length'.

import std.stdio;
void main()
{
    int length;
    char[] foo;

    foo = "derek parnell".dup;
    length = 4;
    while( foo[length] != 'a' )
        foo = foo[1..$];

    writefln("%s", foo);
}
