The documentation doesn't say anything about "in" being a

Thanks,

http://dlang.org/function.html#parameters
it's specified in http://dlang.org/abi.html (at the bottom):
"out and ref are passed as pointers".
The logic seems to be that if it's not specified then it's copied.
Maybe `const ref` is what you're looking for...passed as pointer
but the compiler will prevent writing the parameter, though it's
still possible to take the address and to modify the param if the
function is not @safe.
