This is really a very good site where you can learn new languages, and learn new ideas from others’ codes, review and appreciate each others’ code, etc. This is really a great effort and I enjoy it. I am stuck with the initial exercise named “Bob” because it involves unicode as well. But Perl5 and Go languages do not have “Bob” as the 1st exercise. So, as of now, I have some breathing space. Let us see.
