SPUG: Is Perl for .NET on anyone's radar?

Interesting, and I do like your idea #2.

I work with (among other things) a 15-year old, unix-based turn-key business
system, and perl is the best duct tape for this thing that I know of. 

I'm just finishing up a 4 - 5 thousand-line perl program to do health
monitoring on it.  I really love how hashes and lists can be combined into
ad-hoc composite objects.  Essentially its object-oriented programming without
all the formalization...  Ya gotta love it!

But a lot of the joy of C# development is in using the extremely powerful IDE.
 What I want is the syntax of perl, especially for certain classes of problems
(hey, C# already adopted perl's pattern matching syntax, at least they threw
us that bone!) 

Maybe the simplest answer is to add perl programming constructs to C#.  You
can add operators and methods, but you can't change the syntax of the language
itself.  But you could probably simulate a lot of perl's behavior without
having to take out a second mortgage and go on a sabbatical to get it done. 
Hmmmm.  Maybe I'll take a stab at it!
