Pete,

Thank you for chiming in in support. I felt surrounded and outnumbered...

Indeed, in my mind having two sides of that "coin" is quite natural... and I
feel Rob agrees with us on that... he is just "vehemently" against calling
it "pimpl". 

It is only now that I realize how unfortunate that Pimpl name is... Never
occurred to me before... The funny part wore off and all we are left with is
confusion and disagreement on what it stands for. 

Unfortunately, I do not feel that comfortable with "compiler firewall"
either as IMO it might be even more susceptible to strict interpretation.

If you have your own idiom-generalization solution, do you think we might
joing forces so to speak and to cherry-pick the best bits from the both
variants and come up with something better/simpler?.. Unless the dead simple
Sutter's version at  http://herbsutter.com/gotw/_101/ indeed satisfies the
need.
