[ruby-core:75203] [Ruby trunk Feature#12319] `Module#const_get` does not accept symbol with nested name

Issue #12319 has been updated by Robert A. Heiler.


I am also for keeping symbols simple! I love symbols, I abuse them a
lot in my ruby code to yield special instructions/behaviour such as:

    disable :colours # where disable() is a method

But it would scare me if everyone would start to misuse symbols or
expand their usage too much. You also have to keep in mind that
newcomers are often confused about Strings versus Symbols. And I
think in the old ruby, it was actually not meant that Symbols
would become so exposed (not that I mind it, I myself love code
like the above)

`Module#const_get` accepts non-nested string, nested string, and non-nested symbol:

~~~ruby
class A; class B; class C end end end

A.const_get("B")    # => A::B
A.const_get("B::C") # => A::B::C
A.const_get(:B)     # => A::B
~~~

but does not accept nested symbol:

~~~ruby
A.const_get(:"B::C") # => NameError: wrong constant name B::C
~~~
