defsyntax doesn't work as expected.

[tmccombs]

There are a couple of problems with using defsyntax rather thand define-package-syntax.

First, defsyntax doesn't actually define a variable with the given name, as the documentation suggests. (The documentation seems outdated, it uses :dispatch-macro-character rather than :dispatch-macro-char).

Secondly, use-syntax assumes that the name is the name of a package, and uses package-syntax-name, on the name to get the options rather than just using the name, when it is not in fact a package.
