I actually am ignorant of how this works under the hood for
slices, what triggers element-wise copy vs. assign.
The compiler compiles whatever compiles. Currently only one
mistake (type) is required to compile the wrong thing. With the
fix it would require two mistakes (type and syntax), so the
probability of mistake will be square of current probability. If
the second mistake (syntax) is ruled out (template), the
probability is zero.
Range or array, there are still two ways how it can work. The
idea is to give the choice to programmer instead of the
compiler.
But programmer cannot define new operators on slices.
Cannot define new, but could choose from predefined ones.
