[ruby-core:93353]

Description

$ ruby -e 'p({*nil})'
-e:1: syntax error, unexpected *, expecting '}'
p({*nil})
-e:1: Can't assign to nil
p({*nil})

First syntax error is intended.
But second error message Can't assign to nil is confusing.

This happens with nil, true, false and self.
Other identifiers including keywords don't.
