I took a class on programming languages from Douglas Maurer, who had written a book on SNOBOL. It was out of print, which saved a few dollars for the students, since he provided photocopies. SNOBOL did not look especially practical, but the built-in pattern matching made Awk and Perl that much easier to learn.
(Maurer also composes or composed music. His madrigal "Forty Bucks" set to music the text of a Montgomery County, Maryland, photo enforcement ticket.)
