This is a neat project! I might take a look at this if/when I get started on my dream language. :p

One constructive criticism, which may be only an unpopular opinion, but I find creative operator overloading unnecessarily hard to read. And I don't think my opinion is entirely subjective since, by definition, you have to learn new semantics whereas a good function name would make the meaning obvious. Maybe this syntax would be familiar to people who are already familiar with formal grammar notations?
