Well, actually I completely ignore how new or old it may be, but I ignored its whole existence altogether, so... Whatever, it's study(). Is "to discover" the right verb for such a thing? Who knows... It was brought to my attention by a clpmisc post (perldoc perlfunc away. I didn't know it simply because I can't remember having seen it mentioned anywhere in discussion or example before today. And discussions and examples are very important means for me to learn...
BTW, I selected "User Journal" as a "Journal Topic", because I can't see any that is just "Perl": would there have been a more appropriate one? Is the topic important anyway, or can one safely just stick with "User Journal"?

That’s because it’s only rarely useful and very nearly never a clear win. You may as well never think about it, and it won’t make a difference.
If you want to see another relic burried in perlfunc that’s even less useful, check out reset.

I’m not sure selecting a topic even has any effect at all. Maybe it does on Slashdot (which runs the same software) but not here. I think everyone just leaves that at default.

I think everyone just leaves that at default.study(), although I'd rate it close to it. AIUI there's a difference though: the former has a semantic (side-)effect; the latter is only supposed to be (possibly) useful for speed optimization, but won't change what one's script will do in any way.Also, I saw your links: up until now I used

That’s sort of tautologic, of course; its entire point is the side effect.
the latter is only supposed to be (possibly) useful for speed optimization
I know. However, it takes time itself and rarely usefully speeds up a match, so in the general case, it will cause a speed hit (albeit usually a small one). The circumstances in which it can provide a measurable speed-up are so specific that in practice, the function is useless. And that’s why it doesn’t come up.
do I have just to put
<a>tags manually for anything more complex than that?Yes – Slashcode offers no special markup other than
<ecode>and the<URL:...>thing. But I use Markdown to write HTML in textareas anyway, so I don’t care much.
