Survey results: Underscores

[Brian Goetz]

As most of you probably saw, I ran a one-question survey regarding 
people's opinion on the "underscores" feature from Lambda Leftovers.  
Results (2370 responses) are here:

Summarizing:
  - 66% "yay"
  - 21% "ugh"
  - 12% "meh"

Thanks to those who participated; this is useful data.  We'll probably 
be running more of these.
