Monadic operator

In APL syntax, a monadic operator is an operator with one operand, which is written to the operator's left. Outer Product is usually also considered a monadic operator, even though it is written with two symbols and the operand on the right. A specified axis may also be considered a monadic operator, even though its syntax is anomalous: it is written with brackets, and can apply to the Reduce and Scan operators even though operators are not usually allowed to be operands.
