I'm not arguing about anything, I just have a question. I understand that
with the current method used to export functions, it is not possible to
export a variable to a child whose value begins exactly with the characters
in question. A quick test seems to confirm that:
$ x='() { echo a; }' bash -c 'echo "$x"'
$ x='() { echo a; }' bash -c 'echo "$x"'
() { echo a; }
So is there a way to be able to export variables with arbitrary values,
including '() {' ? Sorry if this has been discussed before.
Thanks
