Avoiding any and all indirection at all costs is not one of these.

"Any and all"? Perhaps not. However, I believe the context here was standard library headers. Those are full of small, often-used functions, so avoiding idioms based on indirection such as pImpl is about as close to a black and white rule as you're ever going to find in the programming world.

Nowhere did I say that pImpls should only be used. That was only one of several strategies I discussed.

The article may have discussed standard headers, but it was neither titled to indicate that it was talking about only standard headers, nor are the problems it discussed localized only to standard headers. My original comment did not limit the discussion to only standard headers.
