How to export parent environment variable to bitbake shell task?

In a bitbake recipe, my shell task needs to export http_proxy to the process it calls. http_proxy is whitelisted in BB_ENV_EXTRAWHITE, so the value exported from the shell which starts bitbake is available in the recipe as ${http_proxy}.

To export it to the child task, I'm doing

export http_proxy = ${http_proxy} my_process

This works, but leaves a feeling of redundant syntax to me. Is this the right way to pass the parent environment variable to a bitbake task?

I think that is proper way of accessing variables from environment in bitbake tasks, please see

http://www.yoctoproject.org/docs/2.4.1/bitbake-user-manual/bitbake-user-manual.html#exporting-variables-to-the-environment. And (in my opinion) Bitbake was designed to isolate from user environment and this - redundant syntax is the price for archive this feature.
