The `void` type is only valid for parameters and return types; other symbols
cannot have the type `void`.
Unicode Operators
=================
Under the `--experimental:unicodeOperators`:option: switch,
these Unicode operators are also parsed as operators::
∙ ∘ × ★ ⊗ ⊘ ⊙ ⊛ ⊠ ⊡ ∩ ∧ ⊓ # same priority as * (multiplication)
± ⊕ ⊖ ⊞ ⊟ ∪ ∨ ⊔ # same priority as + (addition)
If enabled, 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.
.. note:: Due to parser limitations one **cannot** enable this feature via a
pragma `{.experimental: "unicodeOperators".}` reliably.
Top-down type inference
