bool `isArrayOpValid`(Expression `e`);
  Check that there are no uses of arrays without [].
Expression `arrayOp`(BinExp `e`, Scope* `sc`);
Expression `arrayOp`(BinAssignExp `e`, Scope* `sc`);
  Construct the array operation expression, call object.arrayOp!(tiargs)(args). Encode operand types and operations into tiargs using reverse polish notation (RPN) to preserve precedence. Unary operations are prefixed with "u" (`e`.g. "u~"). Pass operand values (slices or scalars) as args.
  Scalar expression sub-trees of `e` are evaluated before calling into druntime to hoist them out of the loop. This is a valid evaluation order as the actual array operations have no side-effect.
bool `isUnaArrayOp`(TOK `op`);
  Test if expression is a unary array `op`.
bool `isBinArrayOp`(TOK `op`);
  Test if expression is a binary array `op`.
bool `isBinAssignArrayOp`(TOK `op`);
  Test if expression is a binary assignment array `op`.
bool `isArrayOpOperand`(Expression `e`);
  Test if operand is a valid array op operand.
ErrorExp `arrayOpInvalidError`(Expression `e`);
  Print error message about invalid array operation.
  Parameters:

  Expression `e` | expression with the invalid array operation

  Returns:
  instance of ErrorExp
