22 b.&.(a.&i.)~(' ',~{.a.){~e.&'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'This would be fast if we could just say ' ' 22 b.&.(a.&i.) ] but we need to check for membership in the letters. So the above verb will first generate a boolean array the same length as y, then generate a literal array of that same length, then match that atom-wise with y . The 22 b.&.(a.&i.) idiom may be fast now, but those mallocs won't be.
