Any chance of us adopting the Mach (and Lites) policy of doing
<sys/macro_help.h> (actually <mach/macro_help.h>), and having some
macros like
#define MACRO_BEGIN do {
#define MACRO_END } while(0) /* or with a ; if you like that */
?
IMHO this actually reduces the amount of obfuscation, because it makes
it clear what the statements are actually there to accomplish, and
keeps the braces from running into/obfuscating braces with meaning.
