That's wrong. Perl classes have inheritance, and they always have had it
since they were introduced in Perl 5.0 (in 1994).

Nope. C structs are data structures. Perl modules are primarily a way to
structure code.

You can have that even in C. One of my first major C programs (back in
the 1980s) was object-oriented (including inheritance). I didn't even
know what "object oriented" meant back then, but the library we used for
the GUI stuff used that style so it felt natural to extend it to
"application level" objects.

Moose just adds syntactic sugar. It may be easier to read (especially
for people used to other OO languages) and save a bit of typing, but it
doesn't add anything you couldn't do in plain Perl5.
