> It's written that way because it stems from relational algebra,

A common misconception (that SQL is a realization of RA instead of barely based on it).

In RA, is in fact `Relation > Operator`



Unless I am grossly misunderstanding your notation, I have always seen RA written with the operator first. Some examples:

You are correct in that is the notation used, but that is not how it goes internally!
