I had the impression the "no-eval" was in fact "no eval or Function", in which case this does not count either.
it's based on the glorious `with` statement and it works like a charm Regards On Mon, Sep 14, 2015 at 11:49 AM, Andrea Giammarchi <[email protected] <mailto:[email protected]>> wrote: without using eval, discussed already months ago On Mon, Sep 14, 2015 at 6:03 AM, Thomas <[email protected] <mailto:[email protected]>> wrote: For those interested, this gist better shows what's being discussed: https://gist.github.com/thomasfoster96/193e7c08aae499f810a1 Ron: Yes, that's already possible - but tagged template strings don't really offer much of an advantage over a function as far as templating goes (IMHO).

Whether or not this would make for a reasonable implementation is left to the reader.
