Re: [Chicken-users] More informative names to srfi units - request from a long-term neophyte

Re: [Chicken-users] More informative names to srfi units - request from a long-term neophyte
John, indeed this is not my point. Felix mentioned heart bleeding about self-evaluating vector on r7rs-tasks page ( https://wiki.call-cc.org/r7rs-tasks). My intention was to stress out that not only conceptual issues create dissatisfaction, but the very fact that chicken great developers can't use chicken on their jobs. Personally I don't have a point whether vector should be self-evaluating or not. It was just a reference to extrapolate to another subject. Sorry for the confusion. 2013/4/9 John Cowan co...@mercury.ccil.org Arthur Maciel scripsit: my heart bleeds not only for self-evaluating vectors in R7RS, What is it with this?

You need (use data-structures) in your code. You don't get that error in the interpreter because it automatically loads the data-structures unit. Best wishes.

Thank you. And sometimes I have to include srfi-1 for drop and others.
