Unfortunately, all spellings that require calling locals() are wrong.
Is this where the potential source of surprising error is? * Explicit / Implicit locals() * To me, the practicality of finding '%' and .format is more important than the convenience of an additional syntax with implicit scope, but is that beside the point?

To my mind is that we have already gone vastly too far in proliferating
near synonyms for templating strings. Right now, I can type:
"My name is %(first)s %(last)s" % (**locals())
Or:
"My name is {first} {last}".format(**locals())
Or:
string.Template("My name is $first $last").substitute(**locals())
And they all mean the same thing, with pretty much the same

I really DO NOT want to spell the same thing as f"..." or !"...", let
alone have every single string magically become a runtime evaluated complex object like "My name is \{first}".
Yes, I know the oddball edge cases each style supports are slightly
different... but that's exactly the problem. It's yet another thing to address an ever-so-slightly different case, where the actual differences are impossible to explain to students; and where there's frankly nothing you can't do with just a couple extra characters using str.format() right now.

I've seen others make similar suggestions, but to my knowledge they didn't include this pleasing brevity aspect.
