A few years back I reported a substantial performance issue with the Python-Textile package. I'll defend my choice of phrasing, "incredibly abysmal performance", with a dictionary.

Incredibly: to a great degree; extremely.

Abysmal: extremely bad; appalling. Very bad, dreadful, awful, terrible, frightful, atrocious, woeful, hopeless, lamentable, laughable, substandard, poor, inadequate, inferior, unsatisfactory; informal rotten, appalling, crummy, lousy, shocking, dire, the pits; British informal duff, a load of pants, pants.

I'm thinking a less offensive (though, my gods, being offended at a bug report with test case and measurable performance deficit…) way to phrase it would have been: "Performance is extremely pants." Of course, few would grok that, either.

Now, the maintainer two years ago mentioned he had a work-in-progress "cleanup" of the codebase. Two years ought to have been enough time to get that pushed out, so I've re-benchmar

1. Pick three fonts. Italic versions of a font are themselves fonts for the purposes of this discussion. One font for headers, one font for content ("copy"), one for accent details (such as captions, blockquotes, etc.) A fixed-width font for code is exempt, 'cause it's code.

2. Look at a book, newspaper, or magazine. Notice the conventions used: headings are typically sans-serif, copy text is typically serif, and accent can be whatever. Sans-serif is difficult to read large blocks of text in; there is no regular horizontal line shape for your eye to follow easily, whereas serif fonts "flatten" themselves into visually distinct lines.

: def inner
	I'm an inner template.  My content, here, represents a "level" template.  No start or end, just the middle.
: end

:def outer
	I'm an outer template.  This is my rising edge.
	: yield
	This is the falling edge.

Ask me your questions, gatekeeper, I am not afraid.

Given the opening and closing times for a store, how would you store that data, then subsequently query it, so as to answer the question: at time X (for example, now,) is the store open or closed?

What are the times?

Open 9:30am Monday, closes 5:30pm Monday. Tuesday through Friday open from 7am until 11pm. Saturday open from 11am to 4pm. Sunday closed.
