Ummm, if $term has the right value in it, why did you say 
  for( -5..@{$term} ) {

Why not just 
  for( -5..$term ) {

I think you got carried away with the specialized idiom of how to force values to be interpolated within strings, such as you used in 
  print "\$term is @{$term}\n";

[download]
But even here you could have just said 
  print "\$term is $term\n";

[download]

The value @{$term} is evaluating to an undefined value, which is somehow getting converted into a value of zero. If I say 

  for( -5..undef ) {

[download]
directly I get nasty warnings "Use of uninitialized value in foreach loop entry at hagen.pl line 36." Also if I use a variable with an undef value.

Why so?
