Hello,

     shouldn't most `std.conv` methods be declared pure ?

Cordially,
Julian.

They should, but many are not automatically checkable. For example, the array-to-array conversion writes to a local temporary and then returns it. Technically that is pure, but the compiler cannot prove that as of this time. I will close this for now.
