Au contraire... it emerged from our discussion of this case:

How should the parser disambiguate
my ($hash,%hash);
try { ... } catch $hash { ... }
? But if we require the comma, we know it's parseable, because map can do it.
But I initially wanted to do without the => ... unfortunately that would
require another keyword to handle the EXPR case and it didn't seem worth it.
