vl-some
(vl-some comparator [ listA [ listB ... ] ]
)
This function verifies all corresponding items
from listA against those from listB (and further lists)
using the comparator function.

Arguments |
comparator
(symbol, function, lambda) function used
for the boolean comparison; must return NIL resp.
non-NIL |

Return |
the last result of comparator function call, or NIL |

Example |
(vl-some '= '(1 2 5 8 9) '(2 3 5 6 7)) returns T (number 5 is in both lists, at same position) |
