I think you just need a reassuring pad on the back here footpad

  • You're looking for a direct case sensitive match and used eq, which is perfect.
  • You want to preserve the order of the values. You could build a hash where the key is the arrayindex of the value. eg my %data = (     1 => 'test1', 2 => 'test2', 3 => 'test3); I would see this as unnecessary complication. The usage of an array is perfectly adequate here.
  • Grep is inefficient yes because it searches ALL the matches and thus always loops your entire list.

    Basically I like the code you've written, it's easy to understand, maintainable, fits it's purpose and didn't take you long to write.
    Now if only all code was as easy this....
