Duck Typing - History

History

Alex Martelli made an early (2000) use of the term in a message to the comp.lang.python newsgroup. He also highlighted misunderstanding of the literal duck test, which may indicate that the term was already in use:

In other words, don't check whether it IS-a duck: check whether it QUACKS-like-a duck, WALKS-like-a duck, etc, etc, depending on exactly what subset of duck-like behaviour you need to play your language-games with.

Famous quotes containing the word history:

    I am ashamed to see what a shallow village tale our so-called History is. How many times must we say Rome, and Paris, and Constantinople! What does Rome know of rat and lizard? What are Olympiads and Consulates to these neighboring systems of being? Nay, what food or experience or succor have they for the Esquimaux seal-hunter, or the Kanaka in his canoe, for the fisherman, the stevedore, the porter?
    Ralph Waldo Emerson (1803–1882)

    False history gets made all day, any day,
    the truth of the new is never on the news
    False history gets written every day
    ...
    the lesbian archaeologist watches herself
    sifting her own life out from the shards she’s piecing,
    asking the clay all questions but her own.
    Adrienne Rich (b. 1929)

    You that would judge me do not judge alone
    This book or that, come to this hallowed place
    Where my friends’ portraits hang and look thereon;
    Ireland’s history in their lineaments trace;
    Think where man’s glory most begins and ends
    And say my glory was I had such friends.
    William Butler Yeats (1865–1939)
