:waifs() Built-In

[biscuitWizard]

Added a builtin that returns all waifs called "waifs()"

It is garbage collector safe and doesn't maintain a reference to waifs.

For example:

;$waif
=> #118  (Generic Waif)
@prop me.test {} +rwc
Property added with value {}.
;me.test = {$waif:new()}
=> {[[class = #118, owner = #2]]}
;waifs()
=> {[[class = #118, owner = #2]]}
;me.test = {} 
=> {}
;waifs()
=> {}

When the game recycles the WAIF it also removes it from the cache of all waif references. This is much faster than the in-moo implementation of searching every property on every object in the game and is much safer.

I've also added an optional argument that lets you specify the type of waif you are looking for:

@prop me.test {} +rwc
Property added with value {}.
;me.test = {$waif:new()}
=> {[[class = #118, owner = #2]]}
;waifs($waif)
=> {[[class = #118, owner = #2]]}
@create $waif named "Mysterious Waif"
You now have Mysterious Waif with object number #64 and parent Generic Waif (#118).
;waifs(#64)
=> {}
;waif_stats()
=> ["pending_recycle" -> 0, "total" -> 0]
;me.test = {#64:new()}
=> {[[class = #64, owner = #2]]}
;waifs(#64)
=> {[[class = #64, owner = #2]]}
;waifs($waif)
=> {}
