+# Normally, I would track this using a variable, like so:
+#
+# COMMA_IF_NOT_FIRST_FLAG=false
+# COMMA_IF_NOT_FIRST() {
+#     $COMMA_IF_NOT_FIRST || echo ","
+#     COMMA_IF_NOT_FIRST_FLAG=true

+# Since this function executes in a subshell, that approach will not work.
+# Instead, we peek inside mo and see what is being processed. If the variable
+# name in moParse() changes, this will need to get updated as well. An
+# alternate variable that is usable is context, but that is in moLoop() and is
+# two levels levels deep instead of just one.
