in thread ref to read-only alias ... why?
You seem to be operating from the point of view that "It's self-evident that literals should create non-modifiable values." Yet that's currently not the case in 50% of the examples I posted.
«1» in «for (1)» could return a non-modifiable value, but it intentionally returns a modifiable value (in a sense) some of the times.
«1..3» in «for (1..3)» could return non-modifiable values, but it returns modifiable values, and it's intentionally not getting changed because people want literals to return modifiable values.
It's not self-evident that literals should create non-modifiable values.
