in reply to Perl in the "Microsoft Research Center"
I'm not quite sure what point you are making.
You are surprised, ok. But other monks probably aren't. Perl is ubiquitous, that means it is everywhere, even at Microsoft. I would expect that it has influenced more than a few design decisions, particularly with the recent design of C#. For instance Eric Gunnerson, a Microsoft Programme Manager for C#, admits to being an "old Perl guy" and has used perl as a benchmark for text processing speed.
The world is full of entities that refuse to line up neatly into stereotypes, and that includes Microsoft.
