It's a slippery slope and thus we strongly discourage it. While not technically an inherent problem, it often becomes one due to poor writing or poor planning; this is something even the most skilled of writers are not immune to.

Basically, it's easier to just not do it than risk messing up and having to rush to fix the problem later.
