You right, it is exactly robustness issue.

I think I understand now why - to use such multi-line macro with 
'bracesless' (that is, one line) case of statements if/for/while. It is 
ugly-looking, but perhaps useful hack.

PS. good thing, we can learn here not just D stuff, but in fact other 
languages tricks as well =)
