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
