If there is need to make the numbers particularly readable to human, in such situations, pretty print should be used. To me, separating array or hash elements with space characters (i.e., what pretty print does) looks very similar to separating numerical digits with separators.

I think given the output of inspect is documented to be a human readable, it's not unreasonably to expect it to be so. I agree it would be nice for pretty print to do it but that doesn't have quite the same smooth experience of just getting nice readable numbers in IRB output by default.

Saying that, is there a mechanism where IRB output gets formatted differently that isn't via inspect, something more localised to IRB? That may be a less far reaching change with the same end result

Feature #18410: Proposal to make inspect include underscores on numerics
https://bugs.ruby-lang.org/issues/18410#change-95395

* Author: brightbits (Michael Baldry)
* Status: Open
* Priority: Normal
----------------------------------------
The documentation for inspect reads "Returns a string containing a human-readable representation of obj." but for large numerical values, while 964218442 is human-readable, 964_218_442 is a lot more readable. The language allows the use of underscores to make numbers more readable, so why should inspect not also honour this?

Happy to provide a patch if this would be an acceptable change.
