I just hope that we can get some operator overloading so that

would be a DIP that adds the option to overload opBinary for

element-wise matrix operations, and * for mtimes, etc. Very
Matlab-like.
I double-checked and noticed that Matlab doesn't actually have
.+/.-, just +/-. Since D's a[] + b[] doesn't seem all that
different from Matlab's a + b, with the restriction that there
needs to be destination memory, it seems like it would be a
confusing to add in another way of doing things. So maybe just
add \ and another operator for matrix multiplication. I don't
really know.
I'd like to second more flexibility around unary and binary
operators, perhaps we can have another keyword for instance
"record" that is essentially a D struct but allows the user to
specify their own operators - it could be included unofficially
at first without impacting the rest of the D language with the
stipulation that it is not used in D's core libraries or in
anything important. This functionality would allow notation
native to different fields in analysis to be used.
An interesting idea, but I don't know if they would go to for it.
If you want more operator overloading on a class, you could put
the class as a member of the "record" and alias this it?
