When the user needs to apply more replacements to the results of previous
replacements, then 'thread-last' could be used like in the first example above.
Otherwise, after adding replacement pairs as args of 'regexp-replace',
replacements should be applied "simultaneously". E.g. in the new version
Julia 1.7: https://lwn.net/SubscriberLink/871486/e4ae97b79d72bb25/
and https://github.com/JuliaLang/julia/pull/40484
the existing function 'replace' has been enhanced to accept
any number of replacement patterns that are applied simultaneously
left to right, e.g.
replace("abc", "c" => "Z", "Z" => "WWW")
returns "abZ", not "abWWW".
