Dops (Direct Operators)

Status

Direct operators are not yet implemented in MARPLE.

Planned syntax

      name ← {body containing ⍺⍺ and/or ⍵⍵}

A dfn is detected as an operator by the presence of ⍺⍺ (left operand) or ⍵⍵ (right operand).

• Monadic operator: contains ⍺⍺ but not ⍵⍵. Takes one operand.
• Dyadic operator: contains both ⍺⍺ and ⍵⍵. Takes two operands.

The derived function uses ⍺ and ⍵ for its arguments as usual.

Workaround

You can pass functions as arguments to dfns by assigning them to names and referencing those names inside the body.
