This could never be useful. Trying to condense as much code as you can 
down to as few lines as possible doesn't actually speed up the 
execution, nor does it make it more readable.

Having logic in the parameter list removes the possibility of properly
documenting it and would be executed no quicker than having it done
separately.

If you're developing a public API as it seems you are, then the need for
proper documentation far outweighs the need to condense all the code
down, even for processes that are as obvious as escaping a string.

In short, there's no good reason for this to exist in any language (as
far as I can see) and would probably add more overhead to the processing
of parameter lists.
