You may also want to read Tom Duff’s comments on the Bourne
shell in his paper on rc(1)—see “Design Principles”.[0]

sh’s bizarre quoting rules are its deepest flaw. Everything
that gets expanded by the shell also gets coerced to a string

bash seems to be an attempt to hack most of Perl on top of
these ugly foundations.
