Actually the first item in the list
is used to determine the cuts:
];._1',hello there,how,are,you today?'
hello there
how
are
you today?
];._1'?hello? there,how,are,you? today?'
hello
there,how,are,you
today

>',' cut 'hello there,how,are,you today?'
hello there
how
are
you today?
cut
' '&$: :([: -.&a: <;._2@,~)
This uses cut also:
];._1',','hello there,how,are,you today?'
hello there
how
are
you today?
Oddly, this doesn't work:
;._1',','hello there,how,are,you today?'
|syntax error
| ;._1',','hello there,how,are,you today?'
