Go doesn't do any implicit type conversions, and it's quite consistent
about that. The only things which are type "converted" are untyped
constants.
I would love for this to work too, by the way, since I often come up with
something like:
var a []interface{}
var b []SomethingConcrete
I would love to be able to assign a to b without having to loop, but it
won't work because their sizes are completely different, so the compiler
can't emit a single conversion of this type, since one structure isn't
safely coercible to the other type. This would be along the lines of
reinterpret_cast<> in c++, which can corrupt memory.
