Yes that is one possible solution to the problem and one that is used by one of the modules that are alread on CPAN. It does however have some problems.

  1. Makes it possible that some hard to find bugs are introduced. For instance a function that takes a list of elements and processes them in someway. If that list contains just one item and that item is a hash ref, the item is interpreted as a named argument which is not what is intended. This can give some strange behaviour and the bug can be hard to track down for the module user.
  2. It creates a special case that can be somewhat un-intuitive for people using the module to create subroutine signatures.
