+1 for _:foo

This (direction) makes creating the query from existent graph easier.

i.e. A user can make a query from existent graph (or graph in his/her mind)
by replacing *just* nodes in question by variables, which is natural.
Without :foo, the user should replace all the bnodes with variables, which 
is an extra burden.
