Patrick Palka <ppalka at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |ppalka at gcc dot gnu.org --- Comment #1 from Patrick Palka <ppalka at gcc dot gnu.org> --- (In reply to rhalbersma from comment #0) > Combining the std::ranges::xxx_view adaptors with the pipeline operator does > not compile, in contrast to the supposedly expression equivalent > std::ranges:views::xxx Hmm, I don't see anything in the spec that would imply views::xxx should be expression-equivalent to xxx_view. What I see is that views::xxx(E) is, for some values of E, expression-equivalent to xxx_view{E}. For instance [range.reverse.overview] says: Given a subexpression E, the expression views::reverse(E) is expression-equivalent to: [...] - Otherwise, equivalent to reverse_view{E}. Could you point me to the relevant bits of the spec that would imply this stronger expression-equivalence?
