Thought this might be a good pipe trick addition, been pining for it
for a while:
[[Mexic|o]]an => <a href=/wiki/Mexico>Mexican</a>
Shouldn't really break anything, because no one would use pipe text
and trailing text together anyway, and this saves a lot of retyping
(which is what pipe tricks are all about, after all).
It's an interesting idea, but I think this proposed syntax
is _way_ too confusing... it's too clever. I would expect
[[Mexic|o]]an to be equivalent to [[Mexic|oan]] and I suspect
others would too.
