Ruby has recently merged namespaces as an experimental feature that is disabled by default, as of this writing.
This is a non-trivial development driven by @matz himself, and mainly implemented by @tagomoris, who just became a Ruby committer (🎉).
The feature has been cooking for a long time, with a first ticket opened a couple of years ago (#19744) and a revised one opened just last week (#21311).

In programming languages, literals are textual representations of values in the source code. This is a syntactical concept.
Some examples:
7 # integer literal| # crystal build foo.cr --release | |
| # ./foo 37.7749 -122.4194 34.0522 -118.2437 | |
| # | |
