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.
