It is, if you have absolute control over the calling environment.

Here is an example Python script:
--------------------------------------------------------
import sys
name = sys.stdin.readline()
print "export name=%s" % name.strip()
--------------------------------------------------------
If you call it like this:
bash$ $(python examplescript)
It'll change the 'name' variable of your shell. It's not really a
generic nor an elegant way of doing this. Heck, it even depends on the
type of shell you're using. If it suits your needs, be happy ;-)

The problem with the world is stupidity. Not saying there should be a
capital punishment for stupidity, but why don't we just take the
safety labels off of everything and let the problem solve itself?
