[% ++val %]
[% val++ %]
[% --val %]
[% val-- %]

Will be supported in TT3.  They are not available in TT2.  They are available 
in CGI::Ex::Template (part of CGI::Ex) which does the majority of TT2 and 
much of TT3.

[paul@www1 ~]$ perl -e 'use CGI::Ex::Template; 
CGI::Ex::Template->new->process(\"[% a++ %][% a++ %][% --a %]\n")'
