m...@.n forms a train which then has nothing to do with agenda (unless the gerund m itself contains @.).
m...@.v is a verb where m...@.v y computes vy to result in a single index which selects a single verb from the gerund m, which is then applied to y. Analogously for x m...@.v y . Historically, m...@.v was defined and implemented before m...@.n . ----- Original Message ----- From: Jose Mario Quintana <josemarioquint...@2bestsystems.com> Date: Thursday, November 19, 2009 8:20 Subject: Re: [Jprogramming] Wrong agenda?
