[Constant]$var2 = 2

We can definitely have attributes on a var like [ValidateNotNull()]$var so extending that further like [ReadOnly()] or [Constant()] doesn’t seem too hard of an ask. The different between an attribute and type here are the parenthesis.

I don’t agree. We currently have scope modifiers. $private: is the only real outlier, but that’s mainly an implementation detail. All the current scope modifiers are just that.

“readonly” is not a scope. Nor is “constant”. Neither of those properties are scopes. They’re properties of a variable.

And yeah, it won’t come naturally. Good. There are irritating caveats and weirdness associated with using readonly or constant variables. Folks who use them should be well aware before they stumble into a day’s worth of needless confusion resulting from careless use.
