Re: ob-calc duplicate stack-element issue

[Heiko Schmidt]

Several times I made exactly similar experiences with ob-calc as you 
mentioned (units, do what I want), nevertheless I decided to be 
dependent of orgmode and I'd really appreciate to use ob-calc for 
"literate calculation".

"Embedded calc" seems interesting but I refuse using more tools or modes 
because they always tend to create open loops which I'm having enough.

I think ob-calc is underestimated in the org-babel world - there is only 
a few documentation on it. It could be of more value to document 
calculations.

Thanks,
Heiko
