if you use vanilla JS, or a number of other non-web languages, you are already familiar with implicit declarations of variants. since QS is interpreted, only, there would be real benefits to adding auto-declarations, and a setting to have all vars implicitly typed as variants. you can still have a symbol table, which would assist with finding typos, but that could be auto-generated.
i get it - some people want restrictive-typing and forced-declarations, and can’t stand typos. i go the other way - i can’t stand writing 20% more code, when the interpreter is already configured to do all the extra work for me.
