[Chicken-users] define-record and define-record-type

[Jeronimo Pellegrini]

Hello,

I see that I can (use srfi-9), but define-record-type is already
available, even if I don't (use) the module. Can I always count on that?
I also see from

http://chicken.wiki.br/manual/Non-standard%20macros%20and%20special%20forms#record-structures

that besides SRFI-9 define-record-type there is also a define-record that
has a somewhat
different interface. Besides the different interface, is there any other
differences between
those? (Memory usage pattern, efficiency etc?)

Thanks,
J.
