Module:LuaCall: Difference between revisions

auto converting argument to number often lead to bug, ex. {{#invoke:LuaCall|call|mw.text.nowiki|0001}}, p.call_s is easier for user to use (and tend to produce less bug) than p.call when all argument is to be string |
You can already force the value to be a string with a leading /, as Template:Nowiki2 already does |
