using unmerged PRs

[Vlad Levenfeld via Digitalmars-d]

I was looking at some of the PRs for DIPs and was wondering how
to go ahead and use them in my code. A few of the forum regulars
have mentioned applying their own patches before, and so I would
like to ask those of you that do, what your preferred method is,
or if this is an all-around bad idea and I should just wait for
the PRs to be merged?
