As someone new to bash, but familiar with regular expressions, it wasn't clear to me that something like \w would not work. This added admonition should hopefully save future on-lookers the same trouble I experienced.
I used the wording from the S/O response that helped me realize my error, but if you'd like to change it, that's fine by me.
