I just found this in the docs at compiler::CBridge.coerce

virtual Expr coerce(Expr expr, CType expected, || onErr)

I was wondering what || meant. Is it supposed to mean |->Void|? Is the comma, as in |,| no longer required when you do choose to use the |'s?

That looks a docCompiler bug, if you look at the source you can see it should be |,|.

Promoted to ticket #554 and assigned to andy

Renamed from Docs question to docCompiler bug with |,| signatures

Ticket resolved in 1.0.42
