[Rd] environmentName

[Gabor Grothendieck]

I noticed the new environmentName in R 2.5.0dev.  Thus I gather that
each environment has:

(1) a name
(2) a hex value

so

1. environmentName gets the name.  Is there any way to set the name?

2. is there any way to get the hex value for an environment other than doing:
       e <- new.env()
       capture.output(e)
