I hate the restriction on modules with static constructors and cyclic
dependencies. IMO it's the most patronizing 'feature' D has. A year or
so ago I ran into this issue during my first (and last) big project in
D. Just last week I started working on it again and replaced everything
that got initialized in a static constructor with stuff akin to
static Foobar foobar(){
static Foobar _foobar;
static bool inited = false;
if(!inited){
_foobar = new Foobar();
_foobar.init();
inited = true;
}
return _foobar;
}
(on a side note, string mixins are turning out to be quite handy)
It killed the cyclic dependency problems, but I expect this pattern
isn't a good thing to have littered all over the place.
