GLOBAL_LIST_EMPTY(bitflag_lists)

/**
|
|
* System for storing bitflags past the 24 limit, making use of an associative list.
|
|
*
|
|
* Macro converts a list of integers into an associative list of bitflag entries for quicker comparison.
|
|
* Example: list(0, 4, 26, 32)) => list( "0" = ( (1<<0) | (1<<4) ), "1" = ( (1<<2) | (1<<8) ) )
|
|
* Lists are cached into a global list of lists to avoid identical duplicates.
|
|
* This system makes value comparisons faster than pairing every element of one list with every element of the other for evaluation.
|
|
*
|
|
* Arguments:
|
|
* * target - List of integers.
