+/// The left shift operator `<<`. Note that because this trait is implemented
+/// for all integer types with multiple right-hand-side types, Rust's type
+/// checker has special handling for `_ << _`, setting the result type for
+/// integer operations to the type of the left-hand-side operand. This means
+/// that though `a << b` and `a.shl(b)` are one and the same from an evaluation
+/// standpoint, they are different when it comes to type inference.
