The following rough code example will get you what you want. The parameter
passed to "caller" tells the function how many frames to go back in the call
stack. The fourth list element (which is number 3, starting at 0) contains
the name of the subroutine at that frame.

Hi,
In the absence of an answer from the more experienced list members, I'll
give it a shot. I don't know what kind of structure is being returned, but
maybe you can use the Data::Dumper module to format the output, inserting
the following two lines (in the appropriate places).
use Data::Du
Let me see if I understand your one-liner...
* the "map" function creates a hash, using the array elements as key names,
automatically eliminating duplicates
* the output from the "keys" function (an array) is compared to the
original array, both in scalar context, so the number of elements wil
for (my $i=0; $i<$n; $i++)
is preferable to
for my $i (0...$n-1)
since the latter creates the entire array and then goes through the
elements, instead of merely going from one integer to the next.
hth!

Hi,
I am one of the beginners list's many voyeurs. Can you explain your code?
Where does the "%found_one" hash get its initial value? I understand that
"@_" represents the list that was passed to the subroutine and that "$_" is
the current list element for each loop iteration. Does your code a
