I don't know what the way forward is for the keyword plugin.
The fact that it can't determine the difference between statement start,
expression(term) start and a context where a keyword is a reserved word
(e.g. "elsif" after a then block, "catch" after a try block) is
problematic. IIRC, you said Zephram recommends Devel::Declare over the
plugin handler for that reason.
Either there's something missing, or it's called too often.

PS - If I understand correctly, the advantage of the plugin handler has
over Devel::Declare is that it's easy to lexically scope the effect. I
wonder if Lexical::Sub and Devel::Declare work together.
