Test case:

--------------------------------
static assert({
    if (0 in [0:0]) {}
    return true;
}());
--------------------------------
x.d(4): Error: cannot evaluate delegate pure nothrow bool()
{
if (0 in [0:0])
{
}
return true;
}
() at compile time
x.d(1): Error: static assert  (delegate pure nothrow bool()
{
if (0 in [0:0])
{
}
return true;
}
()) is not evaluatable at compile time
--------------------------------

Calling 'if((a in b) !is null)' can workaround the problem.
