IMHO no spaces, newlines or other \s-chracters are really needed in a perl
script. 1 newline is needed whenever '#!/usr/bin/perl' at the beginning
can't be avoided.
For example:
#!/usr/bin/perl
print "foo bar blahblah
";
print ( 1 and 1 ) . "\n";
could be rewritten to
#!/usr/bin/perl
print("foo\040bar\040blahblah\n".((1)and(1))."\n");
->no spaces, just a single newline.
perl rulez :-) ...
