Thankful for dlet tip!

It would help if I wish to expand few variables dynamically bound.

Though I found the solution for `rcd-template-eval' as I want global
variables, I am simply not using lexical-binding t in the package.

All I had to do is to isolate the function for template evaluation
into separate package without lexical-binding and now there are no
problems whatsoever, interpolation works well.
