I have no idea how Ton's solution works
Ha ha! This was a common problem back in the good old days. Eugene van der Pijll, even after defeating Ton with his Mad Dutch algorithm to win the TPR(0,5a) infix-to-postfix tournament, never did understand Ton's third-placed solution. Ton was by far the most inventive golfer of that era, often unearthing astonishing hacks from deep study of perl's C implementation.

That was terrifically interesting primo, thanks!
