for them 2 alias you can do this as well

alias -l fill.nicks { did -r vhost 3 | didtok vhost 3 32 $regsubex($str(-,$nick($1,0)),/(.)/g,$+($nick($1,\n),$chr(32))) }

and

alias -l fill.chans { did -r vhost 1 | didtok vhost 1 32 $regsubex($str(-,$chan(0)),/(.)/g,$+($chan(\n),$chr(32))) }

just a diff way to do them.
