Higher order function in bash!

gistfile1.sh

#!/bin/bash

function printit {
    echo "This is from an embedded function: $1"
}

function printthat {
    echo "This is the first line."
    $1 $2
    echo "This is the third line."
}

printthat printit 1

yeah, that's cool!
bash can do a lot worse though. :)
I've seen code that evals code that evals code in a build script -- that wasn't cool anymore.
