Implicits to encourage more Name-dropping.
This creates implicits in cakes across the land from:
String => TermName
String => TypeName
And also from:
Name => NameOps[Name] // lower priority
TermName => NameOps[TermName]
TypeName => NameOps[TypeName]
What this is all about, using "drop" as a motivating example,
is that these should all work:
"abc" drop 1 // "bc": String
("abc": TermName) drop 1 // "bc": TermName
("abc": TypeName) drop 1 // "bc": TypeName
(("abc": TypeName): Name) drop 1 // "bc": Name
But this should not:
("bc": Name) // ambiguity error
This requires drop not being directly on Name; peer implicits
from String => TermName and String => TypeName; implicit
classes to install drop on TermName and TypeName; and a lower
priority implicit class to allow ops on Names.
