I'm currently writing a highly autistic toy language. I tried to write a wc, but my split isn't working correctly (it's just using python's split under the hood), so this counted lines instead of words.
|$ split count @|
This does a transfer from | (stdin/out) to the general data queue ($), split (with no params) does a default python split (or should do, count counts, but outputs to the @ queue, and @| transfers that to stdout.
