Is perl5.005 still a need?

Hello,

I'm working on a new (and almost ready) package version and just
recognized that the test suite fails under 5.005. ;-( The code seems to
work slightly different in perl 5.6 and perl 5.005.

That's the background of my question: we are still trying to support
perl 5.005, and I'd really like to continue this. On the other hand, it
becomes more and more difficult and expensive to do so. So what do you
think: while perl 5.8 is already announced, is version 5.005 still a
need? What versions are you using PerlPoint with? If 5.005, would it be
hard or impossible to install 5.6?

Thanks in advance
