|
||
until Hell freezes over and a new king reigns supreme.
|
||
Given a list of state-functions, states, it will execute the first function.
|
||
Each state-function must take at least a single parameter, a matrix of characters. A state-function
|
||
should edit this matrix in-place, replacing its elements with characters that will later be printed
|
||
to the terminal.
|
||
If this function returns NIL, then it will be removed from state-function list and the next
|
||
function in the list will be run in the next iteration. If no more functions remain, the loop
|
||
terminates.
|
||
If this function returns a list, then the given list will be used as additional parameters to the
|
||
state-function in the next iteration, in addition to the aforementioned matrix.
|
||
If this function returns a function, then the returned function will go to the front of the
|
||
state-function list, and will be ran in the next iteration onward.
|
||
If this function returns anything else, then it’ll simply be run again in the next iteration.
