Hi, Adam. There are some ways to do it. I'm sure there are many more, but I don't remember them right now. Hi, Hans. There's a bug (?) in syst-lua.lua related to \expression in MkIV (xmath and xcomplex aren't defined). Please fix that

something

    local result = CONTEXTLMTXMODE > 0 and
        { "local xmath = xmath local xcomplex = xcomplex return " }
     or { "local xmath =  math local xcomplex = { }      return " }

you can test it

%Temporary hack for MkIV

%Only use it in case \expression ... \relax doesn't work

kind of old (hacky experiment) that one ... i probably need to adapt it to lmtx anyway

\luaexpr and \mathexpr are probably better for this kind of stuff (no need for the % then when the optional format arg is used)

Hans
