I was a bit incorrect, sorry. As the 'include' statement puts the
constants of the Yast module into the scope of module X, it's not
required to use the 'Yast' namespace for accessing the 'Path':
module X
include Yast
r = SCR.execute(Path.new('.target.bash'), '/usr/bin/true')
end
However, the SCR call will be executed only once during module X
evaluation and because you assigned it to a local module variable it is
practically useless - typically you would want it for a constant which
makes is useful after you mix-in the module X into another class or
module where you can make use of it.
