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.
