It is working and in fact it is in a "const pure @safe" function. 
So I will trust it  :-)

Yes, I'm aware of this, the conversion I was doing is as follows:

long[4] -> to! -> int[] ->implicit conv. -> int[2][2].

it is the implicit conversion that was failing, not the to! 
function. I didn't realise this until after bearophile's reply :D
