Hi I'm writing a simple polynomial module which requires addition of polynomials.
I have defined the addition by overloading the function + with an additional method: +(p1::Poly, p2::Poly) = ...# code for the addition I would like to use + now in a reduce call, imagine I have a list of polynomials [p1, p2, p3], calling reduce(+, [p1, p2, p3]) behaves as expected, giving me a polynomial that's the sum of the 3 however, I would also like to cover the edge cases where there's only a single polynomial or no polynomial. I would like the following behaviours, : # reducing with a single polynomial list gives just the polynomial back reduce(+, [p1]) > p1 # reducing with an empty list gives back the 0 polynomial reduce(+, []) > ZeroPoly How might I add such functionality? For the empty list case, how might I annotate the type so Julia is aware that [] means an empty list of polynomials rather than an empty list of Any?
