Lua has developed something which can be used to change the syntax of
the language (syntax not semantic). This might for example allow a
cmake script to be translated during the parsing stage, made by lua
parser, of the document into a lua program equivalent. I haven't used
it might self so I don't know how much work it means but if a
scripting language is to be used to replace CMake language, Lua and
its tokens filtering can be used to ensure backward compatibility
quite easly without needing the maintenance of two language at the
same time.
