We have unfairly overlooked the implementation of the data class by Felix Angelov.

This package implements, using macros:

?? A constant constructor
?? A copyWith method
?? A toString method
?? Type equality

Currently, macros are available under the experiment flag and do not guarantee stable performance, but it's still worth playing around with the package.
