"acts very badly" kinda means the same thing :-)

Back in the 80s, when magazines published benchmarks on the 30 or so C 
compilers, often the Zortech compiler was the fastest, and Borland came in 
second. Despite what the journalist's own data showed, they'd then proceed to 
write in the accompanying text that Borland's was the fastest. It was 
unbelievably frustrating.

It's of very questionable value when you consider that D is not a line oriented 
language at all. There is no correct placement of ; in a sequence of whitespace.
