Go Template seems to be a bit limited. Is there any way we might have e.g. jinja2?

Go Template'ing seems to be limited and makes some rather basic logical flows impossible or very hard to pull off, see here why: golang/go#14992

While in other templating languages the same logical flow isn't trivially doable either, they usually provide possible workarounds that allow a logical flow as in the link above (for example in jinja2: http://stackoverflow.com/questions/4870346/can-a-jinja-variables-scope-extend-beyond-in-an-inner-block ).

Have you therefore considered providing a more powerful templating language like the popular jinja2 as an alternative? I am aware this would introduce an additional python dependency, but right now I can't do many things in the template I would like to do because of the limitations of Go Template...

As has been pointed out, the specific use case I gave is doable thanks to various additions of docker-gen for the available functions.

Still, I wonder if some templating engine that is both more popular and has a richer set of known default functions for people might at least be worth a consideration? If it's feasible at all to add it as an alternative of course..
