If my function named "IWillNotCompile" is run, I get an error stating
"Component!int' and 'Component!int' are not compatible."
If my function named "IWillCompile" is run, there are no errors. They do
the same thing, just written slightly differently.
Any suggestions?
Unlike C++, rvalues cannot be bound to reference parameters even if
reference to const.
Make the parameter 'auto ref' and it will compile:
Component!(T) opBinary(string op)(auto ref Component!(T) rhs)
For auto ref, the function must be a template so that the compiler can
generate by-reference and by-value versions of it depending on whether
the argument is lvalue versus rvalue.
Here is my understanding of the issue:

All that being said, what a horrible error message!
