dfn1 / or \
Create a monadic function which is equivalent to inserting dfn
between each pair of elements in its argument. The function produced by \
records each step in its result, /
returns only the final answer.

1+2+3+4+5 Result: 15 +/(1 2 3 4 5) Result: 15 +\(1 2 3 4 5) Result: (1 3 6 10 15)
The ContextException is thrown if dfn
is not dyadic.
