What about something based on current word, so you could select (or  
type) something then invoke the command? Note that commands don't have  
to be shell scripts. You can use Python directly, if that's the  
language that'll do the work. Assuming you had a command that took  
either Selection or Word as input, it could do something like this:

    #!/usr/bin/env python
    import sys
    import dis
    module = [line.rstrip() for line in sys.stdin.readlines()][0]
    dis.dis(module)

You could also get environment variables using Python  
(os.environ['TM_BLAH']) if you prefer that to using STDIN.

I don't see a TM_CURRENT_DIR, but I do see TM_DIRECTORY. Could that be  
it? In any case, aren't you just switching to the current directory  
which, by definition, won't change anything?

What about a command that uses Selection or Line as input and just runs

    ${TM_PYTHON:-python}

This is equivalent to echoing the current line and piping it to python  
on the command line, which seems to work. Maybe you're wanting  
something fancier.
