## About The Pull Request Ever since we moved to the string format these have been far less usable then I'd like. The usecase of needing to set then update them hasn't come up HERE yet (tho I have a pr in the works that does require it), but it DID on wallening, and I think it's a pretty common usecase. What I've done here is added some wrapper procs and cleaned up the relevant macros to make them more understandable. ## Why It's Good For The Game People should be able to do this without needing to mess with arcane, stateful macros.

/**
|
|
* System for storing bitflags past the 24 limit, making use of an associative list.
|
|
*
|
|
* Macro converts a string of integers into an associative list of bitflag entries for quicker comparison.
|
|
* Example: "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:
|
|
* * read_from - String of integers.
|
|
* * set_into - Variable to set equal to a list of integers
