@jjmeyer0 @ottobackwards Yeah, it's definitely possible to break
expressions that include variables named `match` and `default`, but that's the
danger that I think we have to take for expanding the language. We should make
sure we update the Upgrading.md document with a brief blurb when this PR gets
in.
We probably DO want a script as @ottobackwards suggests, but I don't think
it's required here for this PR. All of this is my $0.02
