I love them and wish I'd had this font to give to my intro students—mistyping a curly for a paren is annoying enough when you're experienced, but when you're new to programming and the error messages are not yet super helpful to you and you can't quickly spot the difference between curlies and parens, it can be a really rough ride.

The rest of the font looks good too! I love a good coding monospace that fully distinguishes all the characters.
