There will be “nesting” in 2.0, that is re-applying a regexp on a  
capture variable.

For example you can do:

    ${1/(.*)Form/${1/…/…/}Field/}

Here the inner substitution on capture 1 would do the CamelCase to  
underscore_case or vice versa.

But chaining regexp substitutions, as what you really asked for, that  
is not presently planned mainly because I don’t like the syntax I  
have been able to come up with for it, and the usefulness is even  
less when nesting is introduced.
