RE: Index of element in array?

use List::MoreUtils qw( first_index );
my $i = first_index { $_ eq 'banana' } list;
 
HOWEVER, you should consider whether you really want to use
indexes into
lists.  In general it is preferred just to iterate over
items in a list
directly.  (See "Perl Best Practices" book from
O'Reilly)

Subject: Index of element in array?



Gurus, 

I'm unable to find this in the Camel, Panther, or Billygoat
books, so
I'll ask you... Is there a Perl function that returns the
index of a
given element in an array?  For example: 

my list = q( apple  banana  pear  grapefruit);
