static array error and a surprise!

[MMagain]

int[3] var=[1,2,3]; 

gives the error:

main.d(153): variable main.main.var is not a static and cannot have static
initializer

I thought int[3] a would be a static array ?

surprise question :D
(sorry about all the questions)
Is it considered good programming to use the c standard modules (like
std.c.stdio) or should, where possible, the non-c standard library modules(like
std.stdio) be used?
