Can the following text be clarified?
Extensions that are loaded together with
wfLoadExtensions(with plural -s) will be cached together.
What does it mean for extensions to be "cached together" and how does it differ from (what I imagine to be the corollary) "cached separately?" How does wfLoadExtensions($exts); differ from foreach($exts as $ext) wfLoadExtension($ext);?
Thanks!
I don't know if it is significantly more efficient in terms of caching to use wfLoadExtensions rather than wfLoadExtension. I'd be interested to know, too.
Also, that comment seems weirdly out of context ("Features"?), something for which I may be partly to blame after merging information about installing extensions (info that's relevant to site admins not developers) into Manual:Extensions/Installation and upgrade. I just added a section about the plural option to that page and would suggest removing the comment on this page. What do you think?
