I was under the impression that this is what "ln" was for.

How do you go about getting a list of existing classes or categories?
Not of the files within one of them, but of the classes themselves?

You've got a basic design problem there, in that "se" as you previously
specified it can already be given multiple words:  it treats two words
as a directory name followed by a file substring.

I take it you want the files that have ALL of the specified words in the
name, in any order, rather than files that have ANY of the words?

ANY of the words is something like:

	se () {
	    setopt localoptions extendedglob noshwordsplit
	    print -l **/(#i)*(${(j:|:)~${(q)*}})*
	} 

ALL of the words, in any order, pretty much requires a loop:

	se () {
	    setopt localoptions extendedglob noshwordsplit
	    local -a possible; possible=( **/(#i)*$1* )
	    shift
	    while (( $# ))
	    do
		possible=( ${(M)possible:#(#i)*$1*} )
		shift
	    done
	    (( $#possible )) && print -l $possible
	} 

Your original question:

I'm going to presume you mean you want this at any place where a file
name would normally be completed.

To accomplish this, you have to create a completer to replace the
supplied `_files' completer.  Something like this:

    _files () {
        local -a possible
        possible=( $(se $words[CURRENT]) )
        if (( $#possible ))
	then
	    compadd -f -U -a -- possible
	else
	    # Copy entire content of supplied _files here
	fi
    }

It's rather too bad that _files doesn't have a _dispatch hook the way
_value and _redirect do ... but even that would apply only in 4.1.x,
not 4.0.x.  

There may be some way to accomplish what you want using a matcher-list
entry, but I haven't been able to work out what it would be.
