I already posted this as a reply to the "Visual Studio & Active State" post...but since it looked like more that a couple were interested...
www.solutionsoft.com has already developed and IDE for Perl called Perl Builder. If I remember correctly as of now it supports Active Perl5. I use it often at work and though I am new to Perl, I find it very helpful in Perl Development.
Suffice to say the I don't like Microsoft. I resent having to pay more for software than I do in living expenses. Solution Soft offers a trial period with their Perl IDE. My own biases towards the MacroSoft Corporation make me hope that they do not corner the market on yet another facet to the Computer/Software Development Industry.
OH YEAH!!! Solution Soft posted word that a Linux Version of their Perl IDE is in the works and should be released soon!!!
