In some links I'm creating, I must add square brackets in the link name (as it is the documentation for a function that has optional arguments, square brackets are traditionally used to show that). But when I do that, the link is displayed 'literally'. Example, if I use
[[[ category:page-name | function(arg1, [arg2]) ]]]
It is not displayed 'function(arg1, [arg2])' as a link, but the line above, with the three brackets showing, and no link. I couldn't find a way to display it as intended, so maybe there is or there should be a escape sequence that would allow me to show the brackets.
(BTW, I suppose, since this is in the wiki site, that the line above itself should be displayed as a link — I didn't enclose it in @s. But that is not happening here).
