@glennj Another interesting one. Could you try running this on your machine:

ok> "example.8th" f:include G:reset

ok> "223.456.7890" clean .s
 0 s: 000000010b01c970 1  2234567890

ok> "223.456.7890" clean .s
 0 G: 000000010adf11c0 1  null
 1 s: 000000010b01c970 1  2234567890

Seems odd that the same code returns different results. I must be making some very silly mistake.

There's something going on in digits:
