+% This macro works well in display math and text math, but still appears with
+% the following three problems:
% \begin{enumerate}
-% \item The skip before ``d'' would still be reserved in ``text fraction'',
-% which is regarded bad. For example, |$\d y/\d x$| produces
-% $\mathrm{d}y/\,\mathrm{d}x$;
+% \item The skip before ``$\d$'' still exists before the denominator in
+% ``text fraction''. This is what we do not hope to see. For example,
+% |$\d y/\d x$| produces $\mathrm{d}y/\,\mathrm{d}x$.
%
-% \item This |\d| command cannot be used out of math mode. In other words,
-% |\d{o}| would not produce ``\d{o}'' in text;
+% \item |\d| is defined as a text accent command in \LaTeXe\ kernel. If we
+% defined like this, |\d{o}| could not produce ``\d{o}'' in text.
%
-% \item The skip between ``d'' and the expression before it can be regarded
-% as a product operator. A product operator is definitely a binary operator.
-%
-% Take |\cdot| ($\cdot$) as an example.
-% A binary operator reserves small skips before and after itself when in
-% ``display math'' or ``text math'' such as $x\cdot y$, but the skips will
-% disappear in ``script math'' or ``script script math'' such as $a^{x\cdot y}$.
-% Thus the small skip should also disappear in script, but |$a^{f(x)\d x}$|
-% still produces $a^{f(x)\,\mathrm{d}x}$ but not $a^{f(x)\d x}$.
+% \item The skip before ``d'' should behave like skips around a binary operator.
+% It should disappear in script math and script script math. For example,
+% |$a+b$| yields $a+b$ while |$^{a+b}$| yields $^{a+b}$, the skips around ``$+$''
+% disappear in superscript. But in the definition above, |$^{f(x)\d x}$|
+% yields $^{f(x)\,\mathrm{d}x}$ but not $^{f(x)\d x}$.
