'perldoc Template::Manual::Directives'
CALL

The CALL directive is similar to GET in evaluating the variable named, but doesn't print the result returned. This can be useful when a variable is bound to a sub-routine or object method which you want to call but aren't interested in the value returned. 

# run tpage tt.just.pop.pl
# expect no numbers
OUTPUT: [% list = [1, 2, 3] %][% CALL list.pop %]

I run a Win32 PPM repository for perl 5.6.x and 5.8.x -- I take requests (README).
