I like to use field names like in the example above. Can I do this in racket?
What I have done most recently is to define a struct with a low-level
constructor with positional arguments, and then define a constructor
procedure with keyword arguments ultimately calls the low-level constructor.
There is often a need for a higher-level constructor anyway, such as for
storing internal information in the struct or performing run-time checks.
But, if you wanted to, you could define a simple macro that defines a
struct constructor that accepts keyword arguments and simply stores
arguments to struct fields without checking or any other added behavior.
