Thanks Xavier. I realize implementation differs. Clearly I can't tap into
the underlying constant resolution with pure Ruby. But I expected that I

Thank you Jan and Sandor. That is basically what I thought, but I had

One thing I would like Ruby to have is a concise literal notation for

/"foo/bar"#=> #
./"foo/bar" #=> #
../"foo/bar" #=> #
So, `/`, `./

Have you heard of `Enumerable#every`? It lets you apply a method call to
all elements of an enumerable. Check it out...
[1,2,3].every + 3 #=> [4,5,6]
[1,2,3].every * 3 #=> [3,6,9]

words.every.upcase!
words #=> ["HELLO", "WORLD"]
