Subject: Re: documentation from inside irb

Thank you!

Gabriel, the only remark is that if I leave  method's name 'help' then 
upon loading irb a warning is issued:

  irb: warn: can't alias help from irb_help.

If 'help' will be renamed to something else, for example, 'hel', then
it is possible to call ri help from command line only if its arguments 
will be quoted:

irb(main):007:0> hel String
TypeError: can't convert Class into String
     from /home/eugen/.irbrc:3:in `system'
     from /home/eugen/.irbrc:3:in `hel'
     from (irb):7
     from :0
irb(main):008:0> hel 'String'
<ri help here>
=> true
