I mean that if const_defined? returns true, then between that code
being executed and the call to const_get, some other piece of code may
remove the constant, resulting in an uncaught NameError.

Yes, we’ve already come to that conclusion. You don’t need to keep
repeating it.
I see that you completely cut out the part about const_defined? not
calling const_missing, which is a rather big part of the problem with
using const_defined? in the first place.

Thank you for building me a straw man. I’ve always wanted one.
I want a way to tell if a class or module has been defined/loaded.
The check would then be to see if X was loaded in your example above,
not X::Y.
An alternative is to check $LOADED_FEATURES. This isn’t
straightforward either, as it doesn’t contain the exact argument given
to require. There are internal functions like rb_provided that could
have been exposed to make it easy to check if a feature had been
loaded/is available.
This part of Ruby is surely inspired by Emacs’ way of doing this, see
http://www.gnu.org/software/emacs/manual/html_node/elisp/Named-Features.html
but doesn’t provide a way to check if a feature has been loaded.
(There’s a difference here, of course, as Ruby implicitly uses the
(expanded) path, with possible suffixes/extensions, of the argument to
require as the feature, not a symbol as Emacs forces you to explicitly
use as an argument to provide.)
To sum up, ruby should provide a method “provided?” that checks if its
argument would return true or false when given as an argument to
require. Provided? would return this results negation.
Checking the presence of constants is a workaround that I’ve been
using in the past, but was recently burned by, as, even in the case of
using defined?, this may travel unwanted paths in the resolution of
such constants.
