Wishmaster is a joke language created by user:Jabutosama. It is a manifestation of philosophical idea that no one can prove or disprove relation of arbitrary actions in cosmic scale.
Syntax is never defined to be anything specific but cam be following.
I wish you close this program.
You cannot prove that me or anyone writing any string, or any arbitrary event in past was instrumental cause of any event in observable universe, as testing such would need omniscience. Some programs are forced to work, for example as next second to come, but some, like true being false, are broken and can never work. There are also truly undefined and undecidable ones like halting problem. In total all programs, by the philosophy, are truly undecidable but trend of reality following simple rules all over makes language in some cases very intuitive and robust.
