Agreed, and which side of the border it's on is a matter of opinion.
Suppose you were writing an INI-style parser - would you include this
feature? I probably wouldn't include arithmetic, as it's usually more
effort than it's worth, but it isn't a bad feature inherently. I'd
definitely not include backreferencing (FOO = "bar", followed by
FOO_LEN = len(FOO) or something), or the ability to chain assignments
(FOO = BAR = 0), so those would be advised against in the convention
docs. On the other hand, a quoted string requirement ("foo\nbar")
makes a huge amount of sense in certain contexts, and I can imagine
implementing quite a lot of a programming language's string literal
syntax.
