 the expression `tt(*(e:'reply=(${REPLY}{1,2})':))' will cause the words

+The form tt(PLUS())var(cmd) has the same effect, but no delimiters appear
+around var(cmd).  Instead, var(cmd) is taken as the longest sequence of
+characters following the tt(PLUS()) that are alphanumeric or underscore.
+Typically var(cmd) will be the name of a shell function that contains the
+appropriate test.  For example,

+example(nt() { [[ $REPLY -nt $NTREF ]] }
