Replace it with tcl::mathop::+
Somewhere earlier in the book, I think I mention that the rest of the
book assumes a "namespace path tcl::mathop" which is why there is that
standalone "+". Was a bad idea in hindsight just to save the clutter of
tcl::mathop:: prefixes everywhere.

You can also access the math functions (i.e., sin(), abs() etc) in a
similar way (they exist in ::tcl::mathfunc::)

I was aware of math operations, but have used them very rarely if ever,
so I didn't make the connection. Most important, I had no idea we could
overload our entire code with all the math operations by importing a
namespace. I'm not sure I like it, but it's good to know.

As usual, I am glad I asked despite my usual hesitation. I always end up
learning when I ask. Many thanks. I really appreciate it.
