By shamanas:

This effectively turns exp into a right-associative operator. If it searches for an Acess as the rvalue, the right value is matched in such a way that the 2 ** 3 ** 2 will be read as

ProductCore {
EXP
l = ProductCore {
EXP
l = 2
r = 3
}
r = 2
}

On the countrary, with the Product rvalue, it becomes

ProductCore {
EXP
l = 2
r = PoductCore {
EXP
l = 3
r = 2
}
}
