Hello

In the
https://isocpp.org/wiki/faq/misc-technical-issues#macros-with-multi-stmts<https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fisocpp.org%2Fwiki%2Ffaq%2Fmisc-technical-issues%23macros-with-multi-stmts&data=02%7C01%7Chsutter%40microsoft.com%7C581e5aed73dc4b0f8b9408d6dd63362e%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C636939815568755534&sdata=RBH%2BP16cUhO10Xh9yp626whDdSzAR3USI96WS2Q4Rq8%3D&reserved=0>
page, in my humble opinion, there shouldn't be a newline between "else" and
"(void)0" or a backslash ("") is missing after else:

#define MYMACRO(a, b)
 if (true) {
 statement1;
 statement2;
 /*...*/
 statementN;
 } else
 (void)0
 ↑ // Intentionally not adding a ; here!

This is a problem because it may puzzle beginners trying to use this very
clever trick. I remember it being correct in the original C++ Faq lite, but
this could be a fictional memory :)

Best,

Benjamin
