scan/2 does not appear to be defined in jq 1.6 and no sample is documented

scan(regex) works
scan(regex; flags) doesn't

Running under debian 8 (jessie) and Ubuntu focal (20.04.1) with jq-linux64 1.6:

$ echo '"#big #Big #bIg #bigs #biG"' | jq '.|scan("#big\S*")'
"#big"
"#bigs"

$ echo '"#big #Big #bIg #bigs #biG"' | jq '.|scan("#big\S*";"i")'
jq: error: scan/2 is not defined at , line 1:
.|scan("#big\S*";"i")
jq: 1 compile error

Also, the online documentation for jq 1.6 shows example only for scan(regex).

Expected to get same positive results I get from test(regex; flags).

Running jq -n 'builtins' reveals the only incidence of "scan" is "scan/1".

Thanks! Otherwise, I absolutely adore this wonderful program!

[edits: clarifying version of jq I'm running and added reference to 'builtins' lacking scan/2]

This is resolved by #1961.

All well and good, but commit b41acdd to #1961 says:

This commit does not belong to any branch on this repository.

and scan/2 is still not implemented in jq-1.6-137-gd18b2d0-dirty, pulled and built today, 1.5 years after it was supposedly resolved, the basis for closing my report #2207.

Thanks,
