[Numpy-discussion] additions to random: innovative names vs. algorithm specification

2010-07-29 Thread Alan G Isaac
Rather than just looking for a new name (e.g., znormal), would it not be better to decide on a syntax for specifying PRNG algorithms? (E.g., MATLAB takes such an approach: http://www.mathworks.com/access/helpdesk/help/techdoc/math/brt5wsv.html) Wouldn't this meet the need for replicability with
