Description

I have binding.irb in a ruby file of my Rails 7.2 app.

I run a RSpec test, enter the binding session, hit n (alias of next as per my .irbrc file) and get the following error:

001> n

Maybe IRB bug!

The same doesn't happen if I enter next instead 🤔

Ps: the w alias works fine

This is because :next, :catch and :break are treated specially. Original names of these commands are :irb_break, :irb_catch and :irb_break.
This will be fixed in #1004. However, I think it's better to have a warning when aliased command name does not exist.

Current workaround is to set IRB.conf[:COMMAND_ALIASES][:n] = :irb_next.
