Hi all,

I got two little questions concerning stacks in `expl3`.

1. What is the best way to build a stack for a sequence?

The naive way would be to use something like

\seq_push:No \l_my_stack_seq \l_my_seq

to push and then

\seq_pop:NN \l_my_stack_seq \l_my_seq

But this doesn't look like a clean usage of `\seq_pop:NN` and
`\seq_push:Nn`.

2. Should there be a higher level interface for stacks of the different
data types in `expl3`?

Hello,

FWIW, one can not dump LaTeX on a virgin system (say D. E. Knuth
engines and fonts) if the following 4 tfm files are missing:

line10.tfm
linew10.tfm
lcircle10.tfm
lcirclew10.tfm

For required/graphics, the driver dvips.def is not anymore generated
by graphics-drivers.ins: it has to be get from contrib/graphics-def.
(Not a problem for me, I know where to find it; but it could be
mentioned in the doc.)

Hello,

I'm the developer of the kerTeX TeX and al. distribution.

kerTeX has, of course TeX and e-TeX, but not other engines.

The first "engine" modification of LaTeX, a few months ago, was to
request the e-TeX extensions and drop vanilla TeX. OK, done.

Now the last modification requires extensions not present in e-TeX.

Until now I was able to provide the kerTeX users with a LaTeX package
(I'm not myself a LaTeX user). I will not be able to follow if this
stays the same way.

While looking into this question https://tex.stackexchange.com/questions/565031/slightly-bigger-integral-in-exponent <https://tex.stackexchange.com/questions/565031/slightly-bigger-integral-in-exponent> I found that the formatting of \int differs slightly when using the amsmath package vs the base LaTeX with the former using a scriptstyle integral while the base uses a textstyle integral.

Given the following equation:

\[
e^{i \int \!dt\,\frac{1}{2}m\dot x^2}
\]

I get

with amsmath loaded and

without it loaded.
