Variants

A function call

The first field resolves to the function itself, and the second field is the list of arguments

A binary operation (For example: a + b, a * b)

A unary operation (For example: !x, *x)

A literal (For example: 1, "foo")

A cast (foo as f64)

Variable reference, possibly containing :: and/or type parameters, e.g. foo::bar::.

An indexing operation (foo[2])

No-op: used solely so we can pretty-print faithfully

If compiling with full support for expression syntax, any expression is allowed
