Hi,
sorry for touching this subject, but I have a question which looks to me
related to the thread.
There is not-empty function in the sequences library.
If not-empty is there should we use it instead of (seq c) to check if a
sequence is not empty?
The doc does not propose to use (not-empty c) instead of (seq c) but what
is the reason of having not-empty then?
Thanks.
