I would love to see better handling of comments containing TT tags. I've been bitten by the TT tags inside comment deal before and now I often just use the following for all my more complex comments:
[% BLOCK comment1 %]commented text[% END %]

Having a [%#* *#%] would be very nice. I would prefer that over the [% COMMENT %]...[% END %] syntax.

Possible bonus points if it can handle comments inside comments. For example by detecting the character after the '#'. ie:
[%#1
  blah...
  [%#0
  foo ...
  [%#* Some other crazy code *#%]
  bar...
  0#%]
1#%]
