Can we fix the fact that the docs are duplicated for template 
functions before any big announcements? See e.g. 
https://dlang.org/library-prerelease/std/algorithm/comparison/among.html from above. This leaves quite the bad impression, as it makes the page look like an unstructured mess at first glance.
