such a standard library would define an *interface* for standard objects. Where performance is an issue, the interface could alternatively implemented with externals. This also is exemplified in [list]-abs, where personally I use a version of [list-drip] that has zexy's [drip] inside for speed reasons. It behaves exactly like the abstraction version so it doesn't matter if people don't have zexy installed.

i just made a pure-pd [list-drip] that is much much quicker for large lists than your pure pd [list-drip].

For a list of size 32768, I find it to be at least 250 times faster.

For a list of size 4096, it's at least 24 times faster.
