That's fairly clever, but it can be simplified to:
PUSH-OMIT-CONTEXT
OMIT 2013-05-19
# Count Sundays from the week before first lesson
# until today. Use max(...) to avoid error if current
# date < 2013-05-05
SET SALSALESSON nonomitted('2013-05-05', max('2013-05-05', today()),
"Mon","Tue","Wed","Thu","Fri","Sat")
REM 2013-05-12 *7 UNTIL 2013-06-23 AT 18:00 DURATION 1:00 SKIP MSG Salsa Level
1 - #[SALSALESSON]
POP-OMIT-CONTEXT

David.
