For clarity I'm going to respond to some potential rewrites of

No. That's the syntax. Even if you customize it in your own
code, by overloading addition or the like, you'll still come
across it in other people's code. So I can only recommend that
you find some way to make it readable for you. Maybe use a
different or larger font? Maybe just get more familiar with it?
I don't think the syntax is likely to change.

It's under 'expressions' in the spec:

You can use it to join arrays in general, including strings.
Depending on your use case you might prefer joiner()
in usage like
assert(["many", "strings"].joiner("").array == "manystrings");
Or Appender, for many mutating appends to the same array:
