This seems like such an obvious idea that I'm having trouble believing
I'm the first to think of it. Why not take ranges containing
Float::INFINITY and translate them to the appropriate greater than or
less than comparisons? Example:
class Person
scope :voters, -> { where(born_on: (-Float::INFINITY..18.years.ago)) }
end
This would generate something along the lines of "WHERE people.born_on
<= '1995-02-19'".
A proof of concept implementation was easy to knock out:

This seems like a intuitive, unobtrusive way to make some comparison
operators available without dropping down to SQL. Tell me why I'm
wrong.
