I think you should show through several exemples. AS IT IS UNIVERSITY, I
guess your public will know about programming.
Explain difference between struct and classes, and how it is great
compared to C++ (no slicing for exemple).
Show some stuffs about first class function and delegates (for callback
for exemple) coppared to how painful it is in C++ or java (using
interface and useless object)
Then, gove a talk aboit metaprogramming (how you can implement behaviral
pattern with no cost at runtime, how you can make very generic code like
STL) and why it is way better than C++ (usability with stuffs like
static if) or java (generic isn't metaprogramming).
And last but not least : explain memory model and how it help to deal
with multithrading problems where other languages usually aren't good.
The point isn't to bash C++ or java, but to show how some problem you
face in thoses languages can be solved elegantly in D.
If your public knows others languages than java and C++, then adapt the
speach to what they know.
