Hello ConTeXist. Is there any way to evaluate of contents of two macros as I am showing in my minimal example? I know, that problem is in expansion, but I dont know to resolve it. My minimal example consist of piece lua code, because I am solving my problem in mixed codes (TeX & Lua) Thanx for help.
