A while back, using unquote inside quasisyntax became deprecated:

Following the warning's advice, however, leads to an error:

Using literal unsyntax instead of #, works, though:

As does using both #` and #,:

The problem appears to be that ReaderDispatchSyntaxQuote#read sets reader.inQuasiSyntax = true when it sees #`, but nothing sets that flag for literal quasisyntax. So in the latter case, when it gets to #, it erroneously calls ReaderDispatchSyntaxQuote#readNamedConstructor.
