IIRC, curlies are necessary for anonymous hash constructions.

Single quotes are quite useful, reducing backwhacks, such as: 

print 'The value of $scalar is ', $scalar, ', and this line ends with 
+\n', "\n";

    I still much prefer:

    print "The value of \$scalar is $scalar, and this line ends with \\n\n
+";

say   "The value of \$scalar is $scalar, and this line ends with \\n";
