      @getify @BrendanEich @RReverser Would you accept (template`look ma a ${str}ing`)("str") -> "look ma a string" ?

      @wycats perhaps this illustrates what i'm getting at slightly better than tweets:https://gist.github.com/getify/405559b860b2c27ff679 …

      @getify Seems pretty easy to polyfill. Do it!

      @wycats i have tried to polyfill it. it can't be done. because it requires dynamic scope. plenty of other tweets earlier tonite about that.

      @getify Wait! You want new Template() to be a new direct eval form?!

      @wycats it's significantly limited compared to general `eval(..)`. it's an eval only for string interpolation of lexical variables.

      @getify but it's a non-keyword that triggers arbitrary eval of remote strings!

      @wycats but the "evaluation of remote strings" is purely string interpolation, no side effects

      @getify the interpolation can be "${anything}"

      @wycats except that it also implies the string interpolation without you needing to put `s in your value

      @getify If you want eval, why not spell it `eval`. var t = new Template("hello ${name}"); function() { var name = "Yehuda"; return eval(t) }

          @wycats go back to the gist i sent you earlier. eval(..) was snippet 1.

          @wycats i don't want eval. i want a very specific thing that's not even remotely as broad as eval. but i've already explained that.

          @getify I don't see any difference between ES5 eval and the restrictions you're proposing here.

          @wycats by ES5 eval, i assume you mean strict direct eval. beyond that, diff is `${ Expression }` vs eval( " Statement " ). big diff.

          @wycats in any case, this is probably a pointless debate. it's clear no one sees my PoV on it.
