Go templates improvement proposal

I have written a proposal for Go to implement the changes that Hugo recently added to a fork of Go’s template packages (mainly to avoid having to maintain this fork). I guess some “thumbs up” on that issue would not hurt:

Note that the above is already in Hugo. Interesting enough, this doesn’t just have functional upsides. I found a new bottle neck that I fixed with this yesterday. And a relevant benchmark comparing the current master source version with v0.61.0 shows great improvements:
