Emmanuel Astier: Did I miss something obvious ?
In the main function, there are :
* a local constexpr called "auto" with value 6.
* a local constexpr called "auto" with value 7.

As the two names are identical ( and how can that be ??? ), why is auto * auto equals to 6*7, and not 7*7, or 6*6 ?

Sylvain Glaize: You missed the Zero Width Whitespace unicode character (U+200B). And I missed that it was not only used at the end, but after each "auto" that is not the keyword.

The function has one. The typedef has two. The variable has 3. The template types have 4, 6 and 7 (for the ... version), the constexpr has 5.

Really, the last lined is read (copied from an editor that shows you what's important) : return auto<200b><200b><200b><200b><200b><200b><200b>*auto<200b><200b><200b><200b>;

Emmanuel Astier: Ah ok !
I was expecting such a trick, but actually, I copied the last line ( auto*auto) into notepad, and couldn't find any whitespaces...

Quite disapointing, in reality...

Thanks !
