How to use enum? to check for existence in sparse array

Hi Alex, Is this a bug or is my understanding of how to use enum? from the documentation not correct. I have a little project where I would like to use 'enum. I was using 'idx before, but 'enum looks like a much better fit. My current problem is that in a sparse array I am getting false positiv

Connecting stderr

Hi, When calling, or piping, to an external process from picolisp, is there a way to connect the stderr of that process on another channel as well, so that it can be read, and distinguished, from stdout. /Lindsay

picolisp db encryption?

Question: Is it possible to encrypt picolisp dbs on the fly? For example, to hook into the low level functions that do block reads and writes in order to apply encryption? For example, it would be a useful option, when setting up a 'pool' to specify a key that is used to decrypt/encrypt block rea

Updated wiki example

Hi, https://picolisp.com/wiki/?RunExe I optimized the code used in the example I previously added to the wiki. Being able to pipe 1M inserts into a sqlite db in ~2.5secs from picolisp is all kinds of awesome. I also added a link to an additional example: https://github.com/thinknlive/picolisp-li
