The `not` keyword is always a unary operator, `a not b` is parsed
as `a(not b)`, not as `(a) not (b)`.
Unicode Operators
-----------------
These Unicode operators are also parsed as operators::
∙ ∘ × ★ ⊗ ⊘ ⊙ ⊛ ⊠ ⊡ ∩ ∧ ⊓ # same priority as * (multiplication)
± ⊕ ⊖ ⊞ ⊟ ∪ ∨ ⊔ # same priority as + (addition)
Unicode operators can be combined with non-Unicode operator
symbols. The usual precedence extensions then apply, for example, `⊠=` is an
assignment like operator just like `*=` is.
No Unicode normalization step is performed.
