Re: $/ not always set after a regex match?

But if a sequence has its own $/, why does * ~~ /9/ set $/?

Actually it's not just sequences, as a little more experimentation showed:

[0] > first /9/, ^Inf
9
[1] > $/
Nil
[2] > grep /9/, ^10
(9)
[3] > $/
Nil

The * ~~ "trick" sets $/ in these cases too.
