Yes it is. The example looks strange because the first character of a is
"a", not normally used as a separator. If the first character is a blank
(say), then it looks more normal. e.g.
state=: 3 2 2$ 1 1 2 1 2 0 2 2 1 0 2 2
a=: ' a good way to start the day'
(0;state;<a.={.a);:a;:a
┌──┬─────┬────┬───┬──────┬────┬────┐
│ a│ good│ way│ to│ start│ the│ day│
└──┴─────┴────┴───┴──────┴────┴────┘
<;.1 a
┌──┬─────┬────┬───┬──────┬────┬────┐
│ a│ good│ way│ to│ start│ the│ day│
└──┴─────┴────┴───┴──────┴────┴────┘
S=: 0;state;<a.={.a
(S&;: -: <;.1) a
1
(S&;: -: <;.1) ' the quick brown fox jumps over the lazy dog'
1
x=: 1e6$' the quick brown fox jumps over the lazy dog'
(S&;: -: <;.1) x
1
Now the thing that surprised me when I saw it the first time:
timer=: 6!:2
10 timer '<;.1 x'
0.0630174
10 timer 'S&;: x'
0.0675069
<;.1 is implemented using hand-coded C.
