Anyway, today I'm not in the mood to ponder semi colons, as it's the least of my worries,
I am very sorry to bother you and other ConTeXt devs with this. If it makes it feel any better, the LaTeX folks seem equally annoyed with me.
I'm not sure what "just %" means here.
These were Joseph Wright's words. I assume Joseph was referring to the fact that in e-TeX and LuaTeX, including a comment after a `\numexpr` causes the comment to be ignored by TeX, similarly to how in LuaLaTeX, including a semicolon causes parts of the following text to be ignored. Here is an example file named `example.tex`: ``` \starttext \the\numexpr 1 + 2; 3 + 4 \stoptext ``` Running `context example.tex` produces the text "7". By contrast, running `context --luatex example.tex` produces the text "3; 3 + 4". Ideally, the two commands would produce the same output.
What does luametatex bring to the latex table?
The expl3 programming language from LaTeX3 can be used in other formats as well, including plain TeX and ConTeXt with LuaTeX, among others. Packages (such as my Markdown package for TeX) use expl3 as a format-independent programming layer. However, since TeX Live 2024, expl3 can no longer be loaded, since LuaMetaTeX's `\numexpr` seems incompatible with e-TeX's and LuaTeX's `\numexpr`. This makes such packages unusable with ConTeXt LMTX, since loading expl3 with `\input expl3-generic` produces the following error: tex error on line 7696 in file expl3-code.tex: Missing number, treated as zero Joseph and I discuss this in https://github.com/latex3/latex3/issues/1518.

Dear ConTeXt developers,
since TeX Live 2024, LaTeX3 can no longer be used with LuaMetaTeX. [1] The issue seems to be that unlike e-TeX and LuaTeX, LuaMetaTeX accepts `;` as part of `\numexpr`. Since `;` is commonly used as a delimiter in LaTeX3, this is a significant issue. The issue would be best solved in LuaMetaTeX by sticking to just `%` like e-TeX and LuaTeX do. Would that be an option?
