I want to pass variable "row" inside function "test" as a read 
only parameter.
Inside I create another variable and try to assign field "text".
On that line I get:
> Error: cannot implicitly convert expression value.text of type 
> const(string[]) to string[].

1. How to assign correctly (and without dup/ugly cast())?
2. Or how to pass "row" correctly?
