Description John Mandeville 2010-10-30 17:00:00 UTC 
The documentation states that this should be an error:

auto s1 = q{ @ };

However, the compiler allows it.

Tested on Windows with 2.040 and 2.050.
Comment 1 Ellery Newcomer 2010-10-30 17:45:09 UTC 
The documentation is not maintained.

If it were, it would say that @ is a valid token in d2.
Comment 2 John Mandeville 2010-10-31 10:34:02 UTC 
Ugh.  I have even used the @ token (which I must have found in TDPL).  That makes me feel dumb.  Well, if it's not a compiler error, then it's a documentation error (in multiple places).  :-)

Sorry bout that :)

FWIW, this problem and a bunch of others are fixed by the patch in bug 1351.

@ is a valid token, and the documentation was recently fixed to reflect that.
