module buggshared;

class A
{
    shared static this()
    {  
        supported["foo"] = "bar";
    }

    __gshared string[string] supported;
}

This builds, which means that__gshared in a class scope implies static?  That
doesn't seem like a good idea.  I didn't find where that's documented either.

Makes sense to me.
How can a class member be __gshared without being static?

Static means there's a single instance.  Shared simply means more than one
thread has visibility to it.  Two very different properties.  Neither implies
the other.

From attributes.html:

"__gshared may also be applied to member variables and local variables. In
these cases, __gshared is equivalent to static, except that the variable is
shared by all threads rather than being thread local."
