I experimented a bit. See the attachment.


The first 3 dumpit outputs are expected. The next 2 are not. The last 2
show what I would have expected from the previous 2.

The $' inside the [] is being used up but not in any way I expected.
Clearly, $'\t' is not representing a tab character, nor is it just using
the $ as a character in its own right. What is it doing?
