In the future you might risk that people think you're a total novice, 
one who doesn't even know the basics of identifiers in C++.

Having called you out on that:

I've not yet heard of a practical problem with it with any compiler. 
However, when Herb Sutter tried this naming scheme on some years after I 
first did it, he got negative reactions from some people whose company 
used a critical custom preprocessing step where `$` was significant, and 
which was sufficiently simple-minded to be misled into doing the Wrong 
Thing™. So he dropped the scheme, but I don't have to. :)

No sane person would e.g. rewrite `#pragma once` to more verbose and 
ugly and error prone include guards with formally guaranteed behavior 
just to get that formal guarantee, but if there is a problem with the 
`$`s, like the aforementioned preprocessing, then you can replace these 
macro names with their uppercase aliases. Less readable IMO. But YMMV.


Cheers & hth.,
