People are assuming stock Lua would be used but I am not so sure about  
that. I guess it would actually be a domain-specific language based on  
Lua: some specific commands and constructs would be needed (sure, they  
would be implemented in Lua or whatever, but you would need to  
document that).

As "DSL based on Lua" != Lua, assuming Kitware gets rid of  
documentation and bugs in the language might be too optimistic. Look  
for example at RHDL (http://rhdl.rubyforge.org/): it's a Ruby-based  
DSL for hardware description, like Verilog or VHDL, but it's so  
different from Ruby you need to produce the whole documentation again.

Talking about Ruby, could someone please paste his wishlist about  
variable scoping for CMake? (ie what would you like to add: local  
variables which die when you exit the loop, file-scoped variables,  
directory-scoped variables, project-scoped variables, what?). It's  
quite difficult to fix a problem we have not properly defined (at  
least, I have never seen a proper wishlist about this).
