I thought “env” here is just a arbitrary key that users themselves may want to have to just group some variables under a single umbrella. What you’re saying is that whatever is under “$.env” is just the exact same environment that we passed when we started the workflow? If yes then it definitely makes sense to me (it just allows to explicitly access environment, not through the implicit variable lookup). Please confirm.</div><div><br></div><div>One thing that I strongly suggest is that we clearly define all reserved keys like “env”, “__actions” etc. I think it’d be better if they all started with the same prefix, for example, double underscore.</div><span class=""><br><blockquote type="cite"><div><div dir="ltr"><div><pre style="margin-top:1.5em;margin-bottom:1.5em;padding:0px;border:0px;vertical-align:baseline"><pre style="margin-top:1.5em;margin-bottom:1.5em;padding:0px;border:0px;vertical-align:baseline"><font face="arial, sans-serif"><span style="white-space:pre-wrap">The nested dict for "__actions" (and all other keys with double underscore) is special system purpose, in this case declaring defaults for action inputs.
