The only thing in non-embind code I can think of is that emscripten looks
for a "Module" variable. If none is found, it is created in the global
scope (because we have no other option). To properly modularize code, it is
enough to do
function myProject(Module) {
// ..emscripten output ..
}
so that Module ends up a local variable.
