[Rd] New pipe operator

Hello,

If Hilbert liked beer, I like "pipe".

More seriously, a new addition like this one is going to cause problems
yet unknown. But it's a good idea to have a pipe operator available. As
someone used to magrittr's data pipelines, I will play with this base
one before making up my mind. I don't expect its behavior to be exactly
like magrittr "%>%" (and it's not). For the moment all I can
say is that
it is something R users are used to and that it now avoids loading a
package.
As for the new way to define anonymous functions, I am less sure. Too
much syntatic sugar? Or am I finding the syntax ugly?

Hope this helps,

Rui Barradas
