I believe Ambrus showed me that trick on the Wiki a few years ago. Or
maybe I picked it up from Raul. Anyway, I wish I could claim credit for
it, but I can't.

What I can claim credit for is a method for evoking a arbitrary string of J
code tacitly (i.e. without using : so there are no problems with u or m or
accessing locally-defined names from within an explicit definition, etc).
The method was overkill for your particular question and I didn't have
access to the scripts on the subway, but if you're interested, see [1] and
and later, building on that work, [2].
