Quackery is an implementation of Quackery.
Other implementations of Quackery.
Quackery is an open source, lightweight, entry level concatenative language for educational and recreational programming.
It is coded as a Python 3 function in under 48k of Pythonscript, half of which is a string of Quackery code.
