 When I saw this proposal, my immediate thought was why not try to
 parse first line of the config file and look for #!/usr/bin/xxx
 there. Or even simply add substitute option to -f that instructs
 squid to "try" to execute (popen) the config file itself. This way
 it should be possible to easily pass arguments and pick preprocessor
 inside the config file itself.

 eg:
   squid -x /etc/squid.conf

more /etc/squid.conf
#!/usr/bin/m4 -E -s
...

 Executable config file this way can show you right away exact same
 final config that would be parsed by squid, expanding all scripting,
 if you test that on a command line.
