Immutable static variables being implicitly non-thread-local is a 
design mistake. Thread-local immutable variables have the same 
right to exist as immutable class/struct instance fields.

This should be possible without hacks:

immutable int val; // thread-specific value

static this() {
    val = ...;
}


...because it is logically the same as:

struct V {
    immutable int val;
}

V val;

static this() {
    val = V(...);
}
