Alternative names for the transitive const regime of D2, the main
difference is that now immutable values are the default:
- "immutable" ==> (nothing, it's the default).
- "const" ==> "valview" (a local immutable value view of something).
- mutable variable ==> "var"
- "enum" ==> "const" (or maybe it can be removed, so it becomes
immutable, that is no annotation. The link-time optimization of LDC is
able to remove unused values from the binary. Ten years from now all D
compilers can be able to do this).
I like the idea, and would like to try D with a system like this.
However, I disagree with the names. See, with my beautiful collection
of bike shed colors, I would keep 'const' for 'const' (for backward-
compatibility and familiarity, and I think valview is an abomination),
and use 'alias' instead of 'enum' (which I still consider the most
glaring error in the history of D).
For transition purposes, 'immutable' could of course be a no-op.
