//{Meaningful section start
...(code to group)
//}Meaningful section end
When I want to group code inside a file, I use:This is an informative message.Code//{Meaningful section start
...(code to group)
//}Meaningful section end
As the brackets are into comments, compiler don't try to parse them and don't throw an error but codeblocks notice them and put an '+' symbol on the margin so I can hide an show this section, regardless of that is not a code section following the language rules.
