(I don't know Russian, hence the following is based entirely on the current translation.) Line 58: "such great mathematicians a" → "such great mathematicians **as**". Line 153-154: the sentence "We...

Frame with both optional and overlay specification can give frame-break

4

A frame can have both an overlay specification in angle brackets and an optional argument. In that order, it works (see frame-A below). But in the other order, one gets...

Use catcode table (cctab) instead of \l__kernel_expl_bool in \ctex_push_file:

2

Currently, `\ctex_push_file:` and `\ctex_pop_file:` (used before/after loading a file) check the LaTeX3 internal boolean `\l__kernel_expl_bool` to determine whether to issue `\ExplSyntaxOn` or `\ExplSyntaxOff` after loading the file. I think that...

Escaping local definitions from groups

21

Sometimes people need to define a token list (or whatever) locally within the group just outside the current group. To do that, a possibility (in want of better names) is...

In LuaTeX, reimplement l3tl-analysis

4

Currently, `\tl_analysis_map_inline:nn` and related functions pollute the hash table by unnecessarily adding active characters to it (explicitly setting them to be undefined), to avoid potential issues with active characters that...

There remains \prop_show:N and log, which means that we cannot really test the code seriously yet. However, it is already exercised as part of the implementation of \prop_concat:NNN and the...

l3keys' .initial:n is not setting \l_keys_key_str

1

When processing `.initial:n`, only `\l_keys_path_str` is set, and not `\l_keys_key_str` (perhaps others are also missing?). This shows up in #1010 in the following MWE: ``` \ExplSyntaxOn \keys_define:nn { my }...

Test if integer is in a range

9

I propose to add an `\int_range_if_in:nn` conditional, used as follows (for instance here I give some true cases) ``` \int_range_if_in:nnTF { [3,40) } { 15 } \TT \FF \int_range_if_in:nnTF {...

Provide regex code callout

2

We are sometimes asked to extend l3regex to have more tests: testing for Greek mathematical letters (#388), testing the meaning of a token, working with grapheme clusters, etc. Some regular...

Do not index \cs_if_exist:N (without TF)

1

Currently, `\cs_if_exist:N` is indexed because it appears in code like ``` \prg_new_eq_conditional:NNn \tl_if_exist:N \cs_if_exist:N { TF , T , F , p } ```
