Yes, it&#x27;s the type glyphs. (For me, at least.) Back when I was a DBA writing database back-up scripts in Perl, I could never remember how to dereference a value in an array or hash properly. (It reminded me of my problem  with pointer notation syntax in C). When I first saw Python, I thought &quot;Wow, it&#x27;s like Perl, but without the confusing notation.&quot; I rewrote the scripts in Python and never looked back.
