Mailfromd TODO list.

* Language:

** Implement \U, \L, \E and other GNU extensions to the replacement strings.

** Various items by Jan (ref <Pine.LNX.4.58.0610112345080.2162@cedric.unob.cz>)

** gsub(regex, repl, string)

** Implement still more string functions

* Provide a library facility:

1. Compile mailfromd source into a position-independent code:

  mailfromd --compile source.mf -osource.mfo

2. Gather several objects into a library using the standard `ar'
   utility:

  ar c file.mfl jeden.mfo dwa.mfo trzy.mfo ...
   
3. Use the archive at the startup to extract the needed functions from
   it:

  mailfromd -lfile   

* Convert database support to MFL

* Implement a separate configuration file, to get rid of `#pragma option' in
filter sources.

* Provide a mechanism to catch exceptions for a given compound statement or
expression.

* Implement nested functions and lambdas:

  set var lambda(string x) returns string
          do
              ...
          done
  apply(%var, "foo")

or:

  apply(lambda(string x) returns string
        do
           ...
        done,
        "foo")

This can then be used to implement the previous topic.
