    \frametitle{ What is Parrot, really? }

    Parrot is many things:

    \begin{itemize}
        \item A culture
        \item A collection of languages
        \item A virtual machine to run said languages
        \item A set of tools to write new languages
        \item A playground for compiler + language research
        \item A second cousin to Perl 6
    \end{itemize}

    Parrot is what you want it to be.

    PMC = Parrot Magic Cookie a.k.a. Objects \\
    Serious people prefer to call them PolyMorphic Containers, but not me

    Meta-recipe:

        \begin{itemize}
            \item \_ cups of \_ flour
            \item \_ \_ eggs
            \item \_ cups of \_ chocolate chips
            \item \_ cups of \_ sugar
            \item \_ sticks of \_ butter
            \item \_ spoons of \_ butter

    Some people like really sweet, dark chocolate chip, peanut butter cookies.

    \begin{center}
        \begin{itemize}
            \item \underline{2} cups of \underline{white} flour
            \item \underline{2 organic} eggs
            \item \underline{1} cup of \underline{dark} chocolate chips
            \item \underline{3} cups of \underline{cane} sugar
            \item \underline{2} sticks of \underline{unsalted} butter
            \item \underline{3} spoons of \underline{peanut} butter
        \end{itemize}
    \end{center}

}

\frame{
    \frametitle{ PMC is for Cookie ... }

    OH NOES! Some people are allergic to peanut butter, dislike processed flour
    and prefer milk chocolate!  Also, almond butter is a delicious replacement
    for peanut butter.

    \begin{center}
        \begin{itemize}
            \item \underline{2} cups of {\color{red} \underline{wheat}} flour
            \item \underline{2 organic} eggs
            \item \underline{1} cup of {\color{red} \underline{milk}} chocolate chips
            \item \underline{3} cups of \underline{cane} sugar
            \item \underline{2} sticks of \underline{unsalted} butter
            \item \underline{3} spoons of {\color{red} \underline{almond}} butter
        \end{itemize}
    \end{center}

}

\frame{
    \frametitle{ The meta-recipe is actually a VTABLE! }

    VTABLE = virtual tables \\

    Examples of actual VTABLEs:\\
    \begin{center}
        \begin{itemize}
            \item get\_integer - get integer representation of PMC
            \item set\_integer - set integer representation of PMC
            \item get\_number - get numeric/float representation
            \item set\_number - set numeric/float representation
            \item elements - get the number of elements
        \end{itemize}
    \end{center}

    Just like no recipe uses every ingredient in your fridge, each PMCs does not implement every VTABLE.

    No stacks! Like Lua VM and Dalvik VM

    Different set of optimizations than stack-based VMs
