} It's a bug if you think the "=" should always indicate an assignment

No, that's not it.

} Otherwise, it looks like
} an expression with a set of globbing qualifiers at the end

Exactly ... the problem is this:

schaefer<508> echo $1+=($2)

} consider an assignment; if it doesn't like it, it will decide it's just
} an ordinary string, so the word will be parsed as a command.

That's just fine, and I don't think it should be changed.
