I'm surprised you expected ('' -:&{. I.0) would be true, as monadic {.
results in a fill when it is given an empty argument. If it had been
decided that {. would result in y when y is empty, then the sentence
in question would be true under the current meaning of -: .
The Match in ('' -:&{. I.0) compares a space with a zero. We don't
want those values to be treated as a match, I think you'll agree.
