This is true.

In this case, perhaps it might be an idea to go all the way,
and remove _. from the parser altogether (making it a spelling error,
and only allowing its creation from foreign sources (or perhaps 3!:2)
since it has no legitimate use in any mainstream J primities
(other than 128!:5) anyway. This has always been the case with
all the other flavours of NaN, and nobody seems to mind.
