Is it possible format the submatch via replaceRE?

Hi, I want to change the case of submatch of replaceRE, something like following.

{{ $s := "http://gohugo.io/docs" }}
{{ replaceRE "^https?://([^/]+).*" "$1" $s }} → GOHUGO.IO, uppercase
2 
{{ $s := "a 1b2 3c4 d" }}
{{ replaceRE `\d(\w)\d` "$1" $s }}

The above returns:

a b c d

If I understand your question correctly, you want it to return:

a B C d

Go’s regex implementation, adhering to RE2, has no provision for changing the case of the submatch.

Yes, that’s what I want, but it seems not supported by Go. Thank you.
