In such cases, beside thinking some time about the topic, one 
solution is to take a look at the asm.

Maybe it's the same problem as with enum arrays, they get copied 
like literals every time you use them.

I think the secondo program, that just calls array(), doesn't 
show a problem that's meant to be fixed.

Regarding the first with filter, I think it's a known temporary 
limitation of CTFE (caused by nested lambdas). I am not sure 
because DMD used to give a more specific error message for this 
limitation.

So I think they don't need to be reported.
