[omitted perl code that loops over lines and evals regexp on each]
Because sometimes you do not want to limit yourself to single lines.
The editing language of sam (and acme's Edit) is much richer -
although I admit I seldomly use its full power (which mostly
shows I'm still not using it to the full power).
Have a look at Rob Pike's "Strucural Regular Expressions",
available via http://c2.com/cgi/wiki?StructuralRegularExpressions .
Axel - who nowadays mostly uses plan9ports acme, using the
patch that makes it do wily style $var substition
