Ok, I've read the bug report following a report from a friend, and after
checking various sources I've come to the following conclusion:

new pure(*[3]) is not valid

When parsed, "new pure(*[3])" is parsed as "new instance of class pure with
parameter *[3]".

Anyway I see no logical reason why one would want to put part of its allocation
into parenthesis.

"new pure*[3]" should be perfectly acceptable, is easier to read, and is
accepted by GCC without problems.


Jonathan Wakely's example with decltype() is non related as decltype() is a new
compiler keyword, which is valid in this context, but has nothing to do with
the original problem.


Anyway I believe  this bug report should be closed before more people spend
time looking at C++ references for this.
