I don't think it's illegal. The spec (Ye Dic, here) is incomplete. It
says what will be done if there is a verb train but is silent about
other trains.
What the implementation does is accept any train and evaluate it.
Thinking about it I don't see anything else you could do with a train; &
I don't see anything bad coming from executing a train containing
non-verbs; so I would vote to expand the spec to include all trains.
There would need to be discussion among The Wise before any such change.

Therefore, the sentence ((<,'"') ` (an 1) (`:6)) is illegal in J because "1
is not a train of verbs (even if it is supported by j). Correct? (This is
not a rhetorical question.)
