There is a lot of code in my project like so:
code:
--------
data SomeThing =
Something { center :: ...
velocity :: ...
...
}
instance Locatable SomeThing where
center = Something.center
instance Moving SomeThing where
velocity = Something.velocity
instance ...
--------
Is there any special extension or syntax trick that would allow me to
reduce the amount of this repetitious code? Someway to implicitly state
that the functions in the data type are equal to the functions in the
class instance, rather than having to spell it out?
