For here +// stands the bastion of the Turbofish: an impenetrable fortress holding +// unshaking against those who would dare suggest the supererogation of the +// Turbofish. +// +// Once I was young and foolish and had the impudence to imagine that I could +// shake free from the coils by which that creature had us tightly bound. I +// dared to suggest that there was a better way: a brighter future, in which +// Rustaceans both new and old could be rid of that vile beast. But alas! In +// my foolhardiness my ignorance was unveiled and my dreams were dashed +// unforgivingly against the rock of syntactic ambiguity. +// +// This humble program, small and insignificant though it might seem, +// demonstrates that to which we had previously cast a blind eye: an ambiguity +// in permitting generic arguments to be provided without the consent of the +// Great Turbofish. Should you be so naïve as to try to revolt against its +// mighty clutches, here shall its wrath be indomitably displayed. This +// program must pass for all eternity: forever watched by the guardian angel +// which gave this beast its name, and stands fundamentally at odds with the +// impetuous rebellion against the Turbofish. +// +// My heart aches in sorrow, for I know I am defeated. Let this be a warning +// to all those who come after: for they too must overcome the impassible +// hurdle of defeating the great beast, championed by a resolute winged +// guardian. +// +// Here stands the Bastion of the Turbofish, a memorial to Anna Harren, +// Guardian Angel of these Hallowed Grounds. <3 + +// See https://github.com/rust-lang/rust/pull/53562 +// and https://github.com/rust-lang/rfcs/pull/2527 +// and https://twitter.com/garblefart/status/1393236602856611843 +// for context. + +fn main() { + let (the, guardian, stands, resolute) = ("the", "Turbofish", "remains", "undefeated"); + let _: (bool, bool) = (the(resolute)); +} -- cgit v1.2.3
