[wp-testers] A Question About 2.7/2.8 argument system

[Paul Robinson]

Yeah, I figured that WP wouldn't parse that the way I thought but it's
mainly for a plugin that I've wrote. I was trying to figure out how WP
accepted multiple values to one key in query string style functions. Then I
realized I was thinking about it too hard and that WP itself probably just
explodes the string at the commas after parsing the query using parse_str();
and that I could probably do exactly the same.

I do it all the time, as my IT teacher once said I always try to avert
occam's razor when I shouldn't. Thanks for explaining that DD32 that should
help a lot with my plugin. :)

Paul.
