Function dmd.arrayop.arrayOp

Construct the array operation expression, call object.arrayOp!(tiargs)(args).

Expression arrayOp (
  BinExp e,
  dmd.dscope.Scope* sc
);

Expression arrayOp (
  BinAssignExp e,
  dmd.dscope.Scope* sc
);

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.
