I know. But if you want a compile-time constant from an expression
there are not many alternatives. It could be hidden behind a macro,
though. In this respect, sizeof dimension<> is better, though still
"size of" has not to be interpreted as "number of bytes of". Somewhere
in the code you should find a commented out #define which had the
purpose to allow using a lowercase "countof" in lieu of "sizeof". Not
acceptable for our guidelines, but you could perhaps use it.
