Outside of Japan, it’s often possible to identify someone by their last name alone (like referring to Albert Einstein simply as “Einstein”), but in Japan, there are so many people with the same last name that this method doesn’t work. After all, there are 600,000 “Matsumoto”s.

He thought Ruby was the best way to do (fill in the blank) and he wanted to share his knowledge as widely as possible. His kindness and generosity extended into every corner of his life. Noah's passing was sudden and very fast. He did not suffer. He is survived by his wife and children.

Noah Gibbs (codefolio, YJIT team, Rebuilding Rails author) has passed away. His big dream in life was to help build the Ruby community up. He wanted to be like the folks who worked to create the railroads during the industrial revolution.

You may call a kind of constant reference "constant path" only when all elements in a reference are constants, i.e., "A::B" or "::A::B::C" can be called constant paths, but "m::D" is not. Because (in my mental model) a path is a chain of static elements.
