Subject: Re: How to suppress display of specific code in irb??

It won't be documented anywhere in the way you're expecting. It's
actually already been explained in these responses.

IRB will print, as the return value, the "last" value of the line you
give it (using inspect), so

1; 2

will return "=> 2" because that's the "last" value of that line.
Adding "; nil" just stops everything before "; nil" from being printed
as output.
