It's certainly handy and easy to remember. But in C we often make the
distinction between "length" (= number of elements that matter) and
"size" (= number of elements for which room is allocated).
The array L"abc" has length 3, as determined by wcslen, but has storage
allocated for 4 elements.

See also the fields 'size' and 'length' in lib/linebuffer.h.

I like the name SIZEOF also because it gets this distinction right.
