Is this internal to the script, or external (looking in)?
I don't think that you can accurately do what you want, because a
script can call multiple interpreters.
#!/bin/bash
echo 'A shellism'
python <<EOF1
print 'This is a python scriptlet'
print 'It can do many things'
EOF1
echo 'another shellism'
perl <<EOF2
{
print "This is a Perl scriptlet\n";
print "It also can do many things\n";
}
EOF2
echo 'a third shellism'

Is "common sense" really valid?
For example, it is "common sense" to white-power racists that
whites are superior to blacks, and that those with brown skins
are mud people.
However, that "common sense" is obviously wrong.
