[0.1.42] ns metadata vs. unused alias inspection

[hlship]

this may be tricky because namespace metadata is normally un-evaluated (unlike metadata on a symbol within the namespace); this metadata is used by the Rook library, which expressly evaluates it. Still, hoping there's an easy way to keep Cursive from thinking the auth alias is not used when it kind of is.

Hmm, I see - this should be a fairly simple fix, the issue is that currently Cursive searches only after the current NS.
