• <<: Is the first numeric or range value scritly left of the second one?
• >>: Is the first numeric or range value strictly right of the second one?
• &<: Is the first numeric or range value not to the right of the second one?
• &>: Is the first numeric or range value not to the left of the second one?
• -|-: Is the first numeric or range value adjacent to the second one?
• <<#: Is the first time value scrictly before the second one?
• #>>: Is the first time value strictly after the second one?
• &<#: Is the first time value not after the second one?
• #&>: Is the first time value not before the second one?

Invalid operations should throw accordingly
