Hi,
I'm looking for a template engine that can give me names of required
variables in parse time.
Calculation of a value for a specific variable name could be possibly done
in specified callback function.
For example:
$title

hello $user/name
#else
hello guest
#endif
list comprehension,
iterators, etc. I tend to avoid such constructs; usually there is a
more natural way to do the same and it's just too easy to get the
indices wrong.
