Extension:

a-^*-b = a-^^^...^^^-a with b ^'s

a-^*-^*-b = a-^*-^^^...^^^-a with b ^'s

a-^*^-b = a-^*-^*-^*-...-^*-^*-^*-a with b -^*'s

a-^*^*-b = a-^*^^^...^^^-a with b ^'s

a-^**-b = a-^*^*^*...^*^*^*-a with b ^*'s

a-^**^**-b = a-^**^*^*^*...^*^*^*-a with b ^*'s

a-^***-b = a-^**^**^**...^**^**^**-a with b ^**'s

a-^*(^)*-b = a^***...***-a with b *'s

More coming soon!
