Yes, exactly. The same could be said for computer graphics, where we traffic in vectors and matricies all day. I want a language in which those are base types, will all of the proper operators already defined, so I don't need operator overloading. Yes, I could write in Fortran, but something a little more modern would be nice.

Fortran is coming up to speed pretty quickly. The 2003 and 2008 updates to it are pretty nice. In fact, I'm in the process of porting the nanomsg sockets library over to it. You can even use GTK3 and Glade to make GUIs for it now, too. I do a lot of matrix calculations, so Fortran is absolutely invaluable.

A simple preprocessor for transforming custom infix operators to method calls might do the trick here. Go comes with good libraries to make this, you wouldn't have to invent a new Go parser. There are other preprocessors that you can look at for inspiration.

That would produce a custom language not understood by other Go users and destroy much of the benefit of the compiler reporting errors straightforwardly.

Sounds very much like the incumbent popular language supporting operator overloading!
