A few very minor library issues

Agree find is a little weird.  I am fine with first() but a little 
squeamish about any(), just because people who have not yet been through 
the parallelism  meat grinder already find "findAny" weird ("why is it 
different from findFirst?")

Also OK with firstElement() and anyElement().

No strong opinion here.  What do people want?
