Description

What problem does this feature solve?

For this demo:

https://jsfiddle.net/2os9jken/

opening the console and running it throws the Interpolation inside attributes has been removed. Use v-bind or the colon shorthand instead. error for the span, but it should also throw it for the slot, as it has the exact same issue for its name attribute.

Research direction
The fix involves adding an error for interpolation in slot name attributes in Vue's compiler. Look for where interpolation in attributes is currently checked (likely for the `span` element) and replicate it for slot names. The relevant code is in the compiler's parsing logic, such as in `src/compiler/parser/index.js`. The JSFiddle demo illustrates the issue; no PRs or assignees are associated.
