Zero. No explicit captures in that pattern.

You're not binding $2:=$1. You're binding $2 to the first
capture. By default $1 is also bound to the first capture.
Assuming that numbered variables aren't special, the orde

get yanked once the final is released (and I think we may start
checking in the final apocalypses and exegeses, but that's for later)
