Ivy is described as a "plaything". Rethinking rules that everyone takes for granted and seeing where it leads seems like a fun way to play. My first CASIO scientific calculator at school didn't understand operator precedence. Since that was how basic calculators worked too, it seemed perfectly natural. I loved that calculator - there was a simplicity and purity to it. When I got a fancier one at uni that had been taught BIDMAS, it took me a long while to get used to, and I never really enjoyed using it. I don't think it was just because the squidgier keys were less satisfying to tap.
