[Jprogramming] Hashing primitives WAS: Farewell for now!

[Henry Rich]

Most people these days seem to like having lots of contributed packages 
to choose from, and don't expect everything to be done in a primitive.

Also, there might not be a clean mapping of the needs of dictionaries 
onto the existing J primitives.

I think your reluctance to use packages is misplaced: for example, bugs 
in calculus can be fixed in the addon, whereas the primitives were never 
going to be updated.
