Thank you for that trick, Chris. Solves my main concerns.
gethash @ ('sha1'&;) &> 'asdf';'as'

with that said, it may be early enough to change to dyad, since the trick is
not as user friendly as not having to use the trick?

Thanks. There are two arguments, so it would have been better to define
gethash as a dyad.
However, I think this is a minor point, since it is always easy to apply a
J function to each element of an array, e.g. as
gethash @ ('sha1'&;)
Each item of the array has its own cd call, so there is little difference
in efficiency.
Also, you are free to define your own gethash function.
