[luatex] LuaMetaTeX ";" syntax in \numexpr

[Joseph Wright]

Hello all,

The current LuaMetaTeX docs say that \numexpr is extended to include
division with truncation using ":". They don't, however, mention that
";" will be interpreted as mod. The new \numexpression includes mod
functionality using "%", although it also seems to accept ";".

Before I make some non-trivial macro changes to allow for this
(https://github.com/latex3/latex3/issues/1518), can I check if ";" is
intended to work but is simply undocumented, or if it's been left as an
oversight and might therefore be dropped from the code  (in favour of "%")?

Regards,

Joseph
