Well, I don't know any way how to define a custom directive. But, there's a way
how to define custom sub, so you are allowed to do something like:
use strict;
use warnings;
use Template;
my $template = Template->new();
sub delete {
delete($template->context()->stash()->{$_[0]});
return;
}
$template->process( \*DATA, { delete => \&delete } ) || print
$template->error();
__DATA__
[% SET foo = 123 -%]
[% IF foo.defined %] foo is now defined [% ELSE %] foo is now undefined [% END
%]
[%- delete('foo') # foo must be in apostrophes %]
[% IF foo.defined %] foo is now defined [% ELSE %] foo is now undefined [% END
%]
It's horrible, but it works ;)

Not really...we have hard-set the TT processor not to allow inline perl. :(
