I remember this kind of thing from days gone by with coffeescript, and the absolute hell it caused. It may have been made worse by js being callback-heavy, but assuming I had a function: def bob(cb, *args): do some stuff... Then the call: bob somefn, 2, 3 Works. But I remember having hellish times tracking down issues when you missed a single comma. bob somefn 2, 3 Now you have bob being passed the result of evaluating the callback (early) with 2, 3 - and this is discovered at runtime. Ugh!
