Thanks Wilco for reminding me that this now replaces a bunch of inline

We did talk about this in Vancouver, including perhaps providing a private
interface. At the time you brushed it off and asked why I couldn't just write
the helpers in C.
My apologies, yes you are right, we did talk about it.
I guess we can talk about a private interface after we see what the total
overhead is with it as it is.
Indeed.
