That message indicates an internal dissect error; an inconsistent
condition was detected.
IIRC dissect has not been upgraded to support the form [email protected] where v
returns rank>0.
That form executes as follows:
1. executes [x] v y to produce an array of selectors s which must be in
the range [-#u,#u) .
2. infers the shape of a cell of [x]/y to be (-@#@$s)}.$[x]/y.
3. collects the argument cells of [x]/y to be operated on by each atom in u.
4. executes the verbs
5. rearranges the results to match the positions of the selectors

Hello forum,
I wrote a small verb:
r =: *`]@.(0: <: ])
This works as expected:
0.1 0.01 r _1 2
_0.1 2
However, it seems to be impossible to visualize the data flow of the
verb with dissect:
dissect '0.1 0.01 (*`]@.(0: <: ])) _1 2'
assertion failure
|assertion failure: inheritu
| 0 e.frame['u failed but u@v succeeded'
Error during initial display
I don't understand exactly, what assertion failed. Is there a problem
with my verb? Or are there currently limitations in dissect which make
it impossible to visualize the data flow?
Thanks in advance for your help.
Regards,
Thomas
