!in operator

[Jacek Nowak]

Hi, I don't know if it's the right place for this, I prefer forums to
newsgroups. Anyway, I am learning D and trying to work with associative arrays.

Code (I'm using v1.065 of the DMD compiler):

int[char[]] arr;

if ("foo" in arr)
{
};

if ("foo" !in arr)              // if (!("foo" in arr)) obviously works
{
};


unfortunately, only the first "if" statement works, while the second one gives
compiler errors:

hello.d|72|found '!' when expecting ')'|
hello.d|72|found 'in' instead of statement|

now, according to http://digitalmars.com/d/1.0/expression.html

"The !in expression is the logical negation of the in operation."

is it a known bug or am I misunderstanding something?
