I don't know about this axis of "magic vs. muggle" we're talking about, but for me the phenomenon we're talking about seems like it can best be described by the ease with which you can find the code that implements specific behavior. Go (and Java) are pretty good at this. Python is OK. Ruby is awful.

This is true except in the case of structural satisfaction for interfaces. You can't trust a rename function in a IDE in go for instance due to this.

And in the case of channel select behavior...and ranges over a channel...and the context object, etc.

My point being "magic" seems to be code for "familiarity with the language and it's idioms". Which I'll grant might be easier in go because of how limiting it is.
