I disagree! I think I see a useful mechanism here, that had never occured to me before.
f=. 0 : 'I=:$0'
More specifically, it occurs to me that 0 : can actually be useful: It is an adjective which asserts that its argument is a noun, which contains no numbers, and which if unboxed would have a rank less than 3, and would contain no further boxes. For example: 'Hi there' (0 :) 'Hi there' 1 (0 :) |domain error: string | 1 string Concise assertions can be quite useful, in some contexts. And, as an added bonus, it can be a syntactically valid mechanism to insert a smiley into a sentence. -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
