OP: "I want readable, modern syntax for If statements, inspired by C."

You: "Don't use If, use &&, which doesn't look like a C If either."

I'm... not following? I mean, yes, the things which you do are valid
bash syntax, and yes, they seem to do what you want them to do, but I
don't *really* understand how they tie in to the premise of the thread.

In contrast, "abuse parser macros" is a valid if terrible answer to the
question of changing the syntax of a bash feature. Something which is
otherwise not really an option, since 40-year-old languages do not
change fundamental syntax on a whim as though they are, I dunno, perl6.

(I am still mindblown that "I want a modern syntax for XXXX" can
possibly lead to "imitate C, which is 50 years old and thus astoundingly
even less modern than the Bourne shell by an entire decade".)
