in reply to Re^2: a natural way of expressing things
in thread a natural way of expressing things

  scalar context list context
grep looks at the entire list and returns the number of times the expression was true returns the list of things that matched
any only looks at as much of the list as it needs to. ie it will stop after the first true condition.

I've never tried a table on PM before. It looks OK(ish) here. Please /msg me if it's a disaster on other platforms.

update: I was using <table border-width=1> instead of border=1. Thanks to holli for noticing.
