First of all, be cautious about premature optimization. In many cases

So, you would like to sometimes go forward, sometimes go backward? If
it is sequential, the list is what you want.

Hi divoplade!
I know there is reverse and I think I did implement it before, when
working through SICP exercises. Thanks for that implementation and input
though!
I think the point I wanted to make is rather to avoid `reverse`
completely. If I had a vector, I could simply go by index backwards or

Hello Guile Users!
I have a question about data structures.
Recently I read a file and the lines in the file would become a list in
my Guile program. The file was not super big or anything. However, I
usually try to avoid having to use `append` or `reverse`, whenever
possible, considering, that t
