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 !
