Perl was also my first productive language, and I do miss it a little. Write something like []string{"foo", "bar", "baz"} in go and you really appreciate qw(foo bar baz). Perl was always designed to be easy to type in, and maybe not so easy to maintain later. Good memories, but not for me anymore.

All of the Quote and Quote-like Operators, and __DATA__, and so many other niceties..
