works too, but

not.
Do you mean the "^" operator or the "^-" operator? Rowan claims that "^"
does not in fact work here...

I'd like to take the /-Operator as the inverse element of an element
relating to multiplication analogous the '-'-Operator for the inverse
relating to addition.
As a compromise, because the left unary / not work, I took '^-' for "to
the power of minus (one)".
It sounds logical, that native operators (4.1.6, Table 4-2) could be not
redefined with other number of arguments (% doesn't work to as left
unary...). But than a miss some documentation hints what are native
operators.
Thanks
Andreas
