Subject: expanding tildes in filenames

Hi all,

Just curious if there's a Ruby idiom out there for automatic tilde expansion
in filenames.  Perl does it like this (taken from the Perl Cookbook, p.
231):

$filename =~ s/{ ^ ~ ( [^/]* ) }
   { $1
         ? (getpwnam($1))[7]
         : ( $ENV{HOME} || $ENV{LOGDIR} || (getpwuid($>))[7])
   }ex;

Will I have to do something similar for Ruby?

How do people feel about adding automatic tilde expansion into the IO class?
In other words, you would be able to do:

IO.foreach("~/djberge/.vimrc"){ |line|
   puts line
}

and it would automatically expand that to your home dir and read your .vimrc
file (for example).

Comments?  Suggestions?

Thanks.

Dan
