I just noticed this works in 2.069, is this intended?
static constructors are supposed to work, yes.
The description is on the class page:
http://dlang.org/class.html#static-constructor
__gshared doesn't do anything there, though. Use `shared
static this` instead, if you want the constructor to run only
once per process, and not once per thread.
__gshared is mostly usefull on fields (eg public uint a)
because it prevents a data to be put on the TLS, which in
certain case reduces the perfs up to 30%. The byte code using a
global variable that's not __gshared can be incredibly slower !
Im' talking about DMD win32 BTW. Even if now I've switched to
full time linux, I have a test on the hold HDD that demonstrates
this :). That's really uncredible. Avoid TLS as possible on DMD
with the switch "-vtls".
