lambda is available, but you have to specify an extra default 
argument _vars=_vars

Even without map and filter this can be useful on occasion if you 
find yourself otherwise repeating an expression a lot of times. On 
the other hand it isn't very pleasant to look at.

I think the answer is probably that if you find you need to use map 
and filter then you should consider using Python instead. Besides 
you can get the effect of both of these with dtml-in.
