I've tried and it works fine. We don't even need to delete the addition c=
ode=20
in motoi_domath, because the operator is discovered and used in motoi_mat=
h,=20
called before.
Ehm... by the way, seems a 20% slower.

This is also funny:

${

    String a =3D "abcdefghilmnopqrstuvz";
    print a[10];

}$

prints 'm' with this operator defined:

char String::[](int index) =3D>
    char mxstr_charAt(const char *s, int index);

while:

${

    String a =3D "abcdefghilmnopqrstuvz";
    a[1] =3D 'z';
    print a;

}$

prints 'azcdefghilmnopqrstuvz' with this other:

char String::[](int index, char c) =3D>
    char mxstr_replaceCharAt2(char *s, int index, char c);
