Log from Silas' email:

Working on Mantis [21349] and think we're missing some tests for inner product. Believe the following should SYNTAX ERROR as f is monadic and does with vectors as arguments.

      ∇ r← f a
[1]  r←a
[2]  ∇

      2 f.+ 4
6
      1 2 f.+ 4 5
SYNTAX ERROR: The function does not take a left argument
      1 2 f.+4 5
          ∧
      1 f.+4 5
SYNTAX ERROR: The function does not take a left argument
      1 f.+4 5
        ∧

Don't know where you've got to with ullu, but case that definitely should be checked!

Not an issue - due to the fact that 6 ≡ f/6 I.e. reduction of scalar doesn't apply the function, and so no error generated.

Can I close this issue then?
