| // Bastion of the Turbofish |
| // ------------------------ |
| // Beware travellers, lest you venture into waters callous and unforgiving, |
| // where hope must be abandoned, ere it is cruelly torn from you. 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 |
