It's a cute idea, though I think the consensus is that once you actually learn a programming language, it generally doesn't help to have it look like prose.
And I think that is really the point of syntax sugar: reading code, not writing code. It seems like a misconception about syntax sugar is that its primary purpose is to make code easier for beginners to learn to write. But I would contend that the real purpose is to make code easier for even experienced programmers to read at a glance, because reading code is actually far more important than writing it.
...granted a certain subsection of the population has determined that reading code is for chumps and boast about how quickly they can use a tool to write lines of code they haven't even read, and that this is the future of software development. Despite their boasts I have yet to see any software I would actually want to use that was written in this manner, though.
Legalese is a bit of a non-sequitur. Despite English legalese ostenisbly being written in English, it is specifically obfuscated, using terminology that is not encountered in everyday English so as to be more difficult for laymen to understand. In fact it is common for legalese to use English that is not English, that is, words that look like English words but have completely different definitions that are not in accord with how those words are used in regular communication.
