If you script is that simpple then take the "#!" line from the top.
ie
~$ cat ~/bin/ccd 
cd ~/src/$1
~$ alias CCD='. ~/bin/ccd' 
~$ CCD perl
~/src/perl$ CCD c
~/src/c$ CCD java
~/src/java$ 

etc etc 

The wreason this works is "." (or source for tcsh) runs in the current shell
ie no fork/exec

If you scripts get more compleicated you need to worry about polution leaking
back into your main shell.
