Because I wouldn't just be using {} on a line, I would create a
dictionary with it and then use it around, and then at some point
later I may want to add another dictionary to it, or find the union or
differences between two dictionaries.

Ruby has this built in, it's useful, it's complete.  It's obvious what
is happening, so it's not unclean.  It's allowed for other containers.
