Hell, they didn't even know about clang even though they were
progressive enough to use C++0x.
I once had a university professor who openly admitted C was the only
language he knew - and yet he didn't even understand how C's
null-terminated
strings work. So he didn't really even know that one language.
Had a workmate who apparently was real good at using C for microprocessor
programming.
But he didn't have the slightest clue about how C++ works and what OOP
overhead really means.
And when I used Lua to create a small conversion script (which was only
needed cause the legacy code was crap, hardcoded paths and the like)
that even turned into some kind of running gag.
I don't need to say that nobody had ever heard of it nor was anyone
willing to try it out before judging.
