In my attempts I have omitted @_ and and was getting Use of uninitialized value $_, but forgotten about when you call it later on without any params. So, that works for multiline comments but not single line. I have put the following test input which I presume is valid Template::Toolkit comment syntax with the exception of nested comments which I am not sure. I will go the Parser way haukex posted. thanks

 [%# comment nust be removed 1 %]
 [% # comment nust be removed 2 
        must stay 0
%]
 [% # comment nust be removed 3
        must stay 1
 %]
 [% # comment nust be removed 4
        must stay 2
        # comment nust be removed 5
        [%# nested comment (not sure if allowed or not) 1 %]
  %]
 [%# 
        comment nust be removed 6
        comment nust be removed 7
        comment nust be removed 8

        [%# nested comment (not sure if allowed or not) 2 %]
  %]
 [% #
        comment nust be removed 9

        [% comment nust be removed 10 %]
        [% # nested comment (not sure if allowed or not) 2 %]
  %]

[% must stay 3 %]
[% must stay 4
        must stay 5
        # comment nust be removed 11
%]

 [% # comment nust be removed 12
        must stay 6
%]
