Hi Per,
Excellent ideas.

Hence I suggest adding:
(string-append! str1 str2)
(string-append! str1 ch2)
or more generally:
(string-append! str1 str-or-char ...)
These modify str1 in place. They return the unspecified value.
Is there any reason to return the unspecified value as opposed to
returning str1 (post-modification)? It seems that returning str1 would
be more useful to a functional programming style. Additionally, this
would make it a drop-in replacement for the existing string-append, in
cases where modification of str1 is not harmful.
Additionally, in analogy to the existing string-append, I would move for
string-append! to take many args rather than just 2, modify the first
one to become the concatenation of all of them, and then return the
first one (modified).
Regards,
Jon
