Re: Class methods and class fields
Yes, this scenario makes sense in principle.
No, I wouldn't use Scheme classes to do templates UNLESS the number
of defaults is large and yet overriding a few of them at a time is
needed. Even then, I'd consider keyword arguments with default values
instead to do what you want to do.
And also see Neil's answer.
