A slurp() function has been specced to slurp a file into a string, as
well as a lines() function that does the same into an array of lines.

You didn't get the point of my Roles idea. It should not be added to a
role File, but to the Role Nameable, which would be composed into
whatever implements file filehandles, but for example also into Unix
sockets. IMNSHO interfaces and implementation should be kept separate
to maintain a proper abstraction level.

You can already easily mix it in using 'does':
$fstab = open('/etc/fstab', :r);
$fstab does WhitespaceTrim;
I don't think it's really necessary to include that into open(),
though it might be useful syntactic sugar.
