local function logCall(fmt, ...)
    local args = {...}
    local parts = {}
    for i = 1, select("#", ...) do
        parts[#parts+1] = tostring(args[i] or select(i, ...))
    end
    setsysvar("LOG_LAST", table.concat(parts, "|"))
end

local function forward(fn, ...)
    if fn == nil then return end
    return fn(...)
end
